Wow, you managed to hold off all contact for a few hours. That'll show her!
So you chatted and that's all it took for you to say "gee I have no plans for NYE either and I miss you too and so I'll come over"? You are one tough dude!
So she LJBF'd you, then after a short time, you agreed to go hang with her, so let me ask you, who do you think now has the power forevermore in this relationship?
There was a gal I was dating since the summer, she was really into me and last week, really drew even closer to me. So we had plans to go out this past Saturday night, but now that she was more emotionally involved, she reacted to my wanting to go out someplace, because she'd rather I stay in with her and snuggle. She took it as a slight, and in her reaction, canceled the date. Big mistake on her part.
I don't tolerate that nonsense, so I went no contact. She texted me, I didn't respond, and then she finally called a couple days later, I let it go to VM, where she left a lengthy apology. I still haven't called her back. In her message she said that she's the loser here, now she regrets acting hastily. I don't know if I want to call her back, but if I do, it's not going to be the same, as I'll be taking that relationship several steps back. Who has the power in this, would you say?
Azonon has it right, BTW. When you have to go No Contact, it's for YOU, not as a tactic to have them come running back, although that's a side effect sometimes. When they realize that they've lost you, if it means anything to them, that's what triggers it. It also lets you know if they really want you or not. Just watch out for the ones that try to get you back only for the sole purpose of dumping you a week later. Women LOVE to have the last word.
