Slick, let me say I was a bit shocked after reading your last post. I know of countless breakups, but when the guy has done nothing blatantly wrong (i.e. cheating), I've rarely seen a girl break up with him in such a bad, disrespectful way.
Slick, I need to get this off my chest right off the bat: this girl is a B I T C H! This breakup is the best thing that ever happened to you. Once you are able to move on, you will look back on this and realize how silly you were to try to cling on to this chick.
Back to the present for now. You could not have handled the breakup worse. Below is a breakdown of your major mistakes from your last post. I'm not writing this to put you down or make you feel like s.hit. What's done is done, and the important thing is that you are no longer dating this wh.ore. However, go through the list and learn from your mistakes, so you won't repeat them in the future.
1. Why did you give her money? for the show? she invited you to the damn thing! For the coat you promised you would buy her? wtf? you gonna keep your promises after she does this to you?
2. You basically realized it was over the night you spend in the hotel with her with no sex/hugging. I would have left that very same night (hey the subway runs 24/7 in nyc for a reason) or early the next morning before she woke up. HOWEVER, in the past I have been in a similar situation, spending one last night with my ex as our relationship unraveled, telling myself it would be fine if we just take it one day at a time, so I can understand why you stuck with it at first.
3. Bitc.hing you out in front of her parents: you should have snapped right there, never let a girl disrespect you, especially in public
4. the whole Macy's/"you can go home now" talk: that was your clue that it was OVER. At that point you should have walked away without even glancing back at her.
5. Instead you go back to the hotel and try to reason with her. You cannot reason with a woman when she is in an emotional state. It's never happened before, and it will never happen. You are using logic, she is using sentiments... It's like you're speaking different languages
6. After she LAUGHS in your face when you mention leaving her, you tell her you "maybe" still want to be with her. wtf (again)?
Slick, I don't know if she has another man. But that is irrelevant at this point. The main reason I see why she broke up with you is because she lost respect in you. Everything she's said or done (that you posted about) is a sh.it test, w/er she did it consciously or not. My guess is she started to notice some incongruities about you a WHILE ago. Women are like sharks: once they sense a little blood in the water, they want more. She probably started throwing a bunch of benign sh.it test at you way before you even noticed anything. Things just escalated, you kept failing her tests, and she kept losing respect for you little by little. When there was none left, she tried to hold it in for some time, but then it all came exploding in your face in the past week or so.
A trivial point: you seemed so puzzled why she wanted you on this vacation so bad, yet at the same time wanted you out of her life: her parents organized the whole thing, she felt bad canceling the whole thing because of them.
No Contact
Slick, from reading one of your earlier posts, it seems to me that you have the wrong notion of what No Contact is. No Contact is a defense mechanism that seals off the source of your pain (you ex) until you recover emotionally from the breakup. Yes, No Contact sometimes works to rekindle attraction. Sure, some guys have got their girl back. But the relationship is never the same. You cannot go back and erase everything that happened. You cannot change the fact that she treated you worse than trash.
Given your present emotional state, the first week or two will be the hardest. You should simply erase all her messages/voicemails without even looking at them. Of course, no picking up the phone or calling her back. It might only take you a few days, or a few weeks, but you will start seeing the light at the end of the tunnel. At that point you start sarging again, hopefully you know a competent wingman, and start bagging chicks again. You still want to maintain no contact, but since you two live in the same city a chance encounter is possible. Be polite with her, acting indiferent but don't go overboard to show her that you don't care about her. Do not engage, especially if she's pushing you. Instead, keep the convo short and eject, telling her that you have to be somewhere. The look on her face will be priceless.
Finally, no contact will NOT work, unless you are convinced that your life is better off without this girl. As long as you are still clinging on to the hope that she will take you back, you will not be able to pull the No Contact thing, you will crack at one point, you will talk to her, she will sound all sweet, and you will be back here starting a thread "Ex giving me positive signals... How to get her back?"
My last relationship, the break up was bad, with a lot of fighting and a lot of heavy words being exchanged. I endured quite some disrespect, in retrospect, sometimes standing up to it, sometimes just letting it slide. I was feeling miserable, hoping to salvage the relationship even though I knew deep down that it would not be possible. However, after I worked out my own issues and dilemmas and decided I would be better off without her in my life, I never looked back. 2 1/2 years later my ex still calls/txt me! The other day I picked up a "blocked ID" call and guess who it was? When I realized that I hung up, only for her to blow my cell for the next couple hours.
My last pitch for no contact: it is the only way to get back to her, at least in the short term. I am sure that one part of you wants to get some sort of revenge on this chick. Well, silence is a woman's number 1 ennemy. Sure, if she would see you strolling down the Village in a Maserati, or eating at a posh place with an uber-hottie she would be even more jealous/remorseful/ hurt. But you won't be doing any of those things in the next few days/weeks, as you try to get your life back together. So the next best choice is to make her guess what you're doing. A woman's imagination is also one of her ennemies in a situation like this. She expects you to be crying, waiting by the phone for her call. She waits a few days, then she does call you. She's curious to see if she was right, she wants to keep exercising her power over you, she wants to stir you up, etc... : at this point she sees you as nothing more than a toy. However, against her expectations, you don't pick up her call! You don't call her back! You don't answer her txts! Right away, the image she made of you in her mind is unraveling.
She will start thinking "maybe he s got somebody else" or "maybe he really doesn't care about me anymore" or something llike that. That's when she ll blow up your phone. Don't make the mistake to think she is actually in love with you again. You simply intrigued her enough that her IL is rising again. The trick is though: if you do take her back, you are conceding to her tactics. Very soon her IL will be down again and the whole sh.it test/disrespect story will play out again. Again, some pple advocate taking her back at this point as a FB, just sex no strings attached. But how realistic is that scenario?
Anyways, I realize this is a huge post, but I hope it was somewhat helpful.
Good luck!
