first, most of pua material focus on the initial attraction phase. most of the tricks, the mindset, how do you carry yourself, what you choose to show is taught for getting as much sex as possible. now, we all can agree that sex can be awesome but at a certain point you need more than that. in my position and in my life right now i'm looking for a meaningful relationship, maybe not marriage and children but someone that brings lightness and good experiences in my life. that leads to point two:
You are correct that PUA material focuses on the initial attraction phase. This is not a bad thing though, because you'll be able to go out there and get damn near any woman you want. It also gives you the confidence you need after a breakup; You KNOW you can go out and get another woman.
The meaningful relationship part is still IMO a long way off for you. You're going to get a few more heartbreaks before you find that. The most important thing you need is a woman who make you her #1 priority. Most women out there won't do that because they've been riding the c0ck carousel and know you're replaceable.
i think that if you wanna have a good girl beside you, first you need to screen and to ditch out immediately the bad ones, and second you need to be able to mantain attraction, or, in this case, do not slip up. for doing this you need a strong frame and a strong identity, a strong self-image. you need to put masculine energy in the relationship and not be overwhelmed by emotions. and here is where i fail.
There are a lot of things you need to do to maintain attraction. You need to work on yourself first. This is where I did a lot of experimentation in my life. I would amplify some parts of my personality and see how people (especially women) reacted to it. It helps if you work with a lot of women. In my case, I ended up with an additional part-time job in a fast food joint. I found that women reacted to me much better when I amplified my enthusiasm and my sense of humour. With that being said, I focused on amplifying those two personality traits in my daily interactions. Now they're pretty much permanently part of my personality. I'm an enjoyable person to be around, and I can easily draw people in.
You need to find out what your best qualities are that make people react to you better, and amplify them. Get what you've already got going to you and improve it. This will help overshadow the parts of your personality that you're struggling with.
i show them my emotions and my past, the processed emotions that are good to share, and the unprocessed ones that show my fears and my insecurities,
Yeah, that's the stuff you need to hold back on. If they start asking questions that lead to these things, you can give her vague answers, funny answers (like David DeAngelo suggests), or steer the conversation towards something else. If you need to talk about your problems, you're better off doing it on Sosuave.
i became a little dependent when i share those things because i trust the other person and i tend to lean on them emotionally,
One thing you need to learn is that YOU are the only person you can depend on and trust. You cannot do it with anybody else. You need to go out and do things because YOU want to do them. You can invite people along with you, but if they cancel, it doesn't mean you should also cancel. Once you learn to do things on your own regardless of other people, you learn to be self-sufficient and independent. This IMO is necessary for a man to learn.
i text too much, and worse i often have meaningful discussion by text (not because i'm afraid to talk with the other person, just because in that moment i'm texting and for me it was a good idea to talk of important topics via text. after all i write often and i like this way of communicate, but in this case it's wrong)
I don't believe that the whole "texting too much" problem actually exists. It's not how much you text, it's WHAT you text. If you make your texts interesting, then she's always going to enjoy hearing from you. You can be funny, you can tease, and you can be sexual through texting. What you need to avoid is being boring through your texts. The only one who should be holding a deep conversation through texting is HER. The best thing you can do is acknowledge what she's saying when she does this. Then steer the conversation towards something that makes her feel good. Once you get her there, end the conversation.
You're well on your way to being a great man. The fact that you've already taken the first step towards improving your interactions with women proves that you can make changes to yourself. You still have a lot of work ahead of you, but I'm certain that you'll be able to do it.
