I'm interested in how you approach the situation when she wanted to be comforted while being angry.
So this was a great girl, full of energy, very sexy and great fun in bed, but a bit of a handful when she got emotional. And she would sometimes get very wound up about something and try to force me to give her attention by seizing the frame like a tiger and trying to get me to 'comply' with her demands, which weren't all that clear.
One time in particular, when we went on a sailing trip I didn't bring something it turned out we needed, and when we got back she went beserk, shouting aggressively. Even though I took complete responsibility, any comment I made on her attitude she considered to be me 'turning it on her'.
Obviously this is typical relationship shit-testing, especially since I was self-employed at the time and not doing all that great, and my frame was shall we say 'under development', but I'm guessing it was on a different level to what most guys deal with. I could see in the family dynamic that her father was very easygoing, dominated by her mother, and protective of his daughter, and her mother a very strong personality and there was always friction and drama with her daughter that you could never tell if it was good or bad. This isn't the best type of upbringing to find a girlfriend with, I believe it causes her to have a bad sense of boundaries, but that said, they are all very good people and her parents together since they were young, so she was brought up with some good values about family and relationships in general.
Anyway, so a few times I didn't deal well with her behaviour, and it got worse. Until one time, I threw her out on the street (she was living with me) when she was so confrontational I thought she would get physical. I'd already told her (at a different time when she asked curiously what would cause me to end a relationship) that a woman hitting me was one of the things that would automatically end things, because I was not interested in either retaliating or accepting it. And I meant it. So it was partly to save her from herself and give her a chance to see what it would be like if she pissed me off too much, without it being the end of things.
This was something I had read about in one of Chase's articles, and it made sense. I don't know if that was the right move, it wasn't easy for either of us, but I think the results were in its favor. She definitely behaved afterward as if there were limits on what she could do, no matter how much she wanted to vent. And she regularly alluded to my 'strong personality' in positive ways afterward.
But while this was a good way to set hard boundaries, the main problem was that she expected a lot of attention when something upset her, regardless of her behavior. The simplest thing I did was to not give her that attention - while telling her how she could get it. I would calmly tell her that I wasn't going to get into a shouting match with her, that I wanted to hear her out but we could talk about it when she calmed down, and then I'd go and do something else and ignore her.
This way of verbally clarifying and then acting on a principle, rather than just getting into an escalating competition, is something Chase often talks about in articles, and it's an extremely good method because it isn't cold (you tell her clearly why it is the case) but it is very firm. It worked wonders. When she saw me set a clear frame and then walk off she would lose steam very quickly and start floundering around trying to negotiate for my attention. She would even keep stomping past me grumbling about how I 'always do X with her' trying to get my attention again.
Another thing I learned from Chase is to always make sure you understand what the problem is (by getting her to clarify it to you, and helping her to clarify it, and actually trying to understand it) before trying to bring up anything she did wrong. It's something Jordan Peterson deserves a mention for as well, I was watching a lot of his stuff at the time as I tried to develop my internal frame and he talks about this in a very articulate way. This is very good for giving her the feeling that I am looking out for her wellbeing rather than simply trying to be dominant. Some girls, like this one, become angry and kind of vicious when they feel scorned in any way, and it's important to avoid putting her in that state by bringing out a problem and dealing with it before it becomes a storm. It took some patience because I have a short temper and sometimes I just wanted to come down hard on her.
I tried a lot of methods with this girl, which all essentially boil down to setting a frame in which both out needs were met, clarifying it to her, and sticking to it no matter what. And when I did that well, it worked spectacularly.
One last thing that looking back was extremely effective, and probably my biggest failure in the relationship, was to reward her when she behaved well. Like many guys I took her for granted a bit when she did nice things for me, when I should have stamped in her mind that it was exactly what I valued from her. I really wish I had done this better, since she was very hungry for validation, and when things were good between us, she was a wonderful woman. Very diligent and responsible, enthusiastic, adventurous and always game to try a new experience with me. I think I could have avoided some bad episodes just by making sure I met her needs better when things were going well.
She still calls or messages me every once in a while and wants to get back with me, but I think our personalities don't mesh together well enough, which is what caused things to end.
Interestingly, I heard that she recently dumped a guy who got very reactive when she shit tested him and responded with a nasty insult, really hurting her. So that's kind of the opposite of everything I've mentioned here, and something that I think doesn't work especially with this kind of girl, since she has a lot of pride.
That's about all I can think of. In this relationship, it was very much me trying to learn fast, and manage things consciously and with my eyes open. I've always liked women who have a strong will to get what they want, the kind who don't settle or submit easily, but I didn't always know how to deal with them, and the main thing I value from Girls Chase is not just helping me build a great frame but making me realize how much I enjoy managing them, since they are the best and most satisfying companions when you have their respect.
Hope this was useful!
