I tend to agree with Lena, and I'll say why.
I think you are uncomfortable with rejection and you fear it happening again. To pull some examples from my faulty alcohol-fueled memory, let me name a few instances.
One of the first girls you were with, she was a Gypsy if I remember right? And you pimped her out to a family member? And then afterwards you felt disgusted, like "how could she stoop so low?" And you lost value. It's actually hard to blame you there, but I think in the male-female dynamic, usually the guy is in control. And so in a sense, you caused it to yourself. Maybe you would have liked for her to decline that, and maybe your takeaway was that women are almost like mindless creatures.
You are also used to being betrayed by the fembois you were with. If my memory is right, the one Russian basically ran off with your money even though you lavished him. You had felt devastated and betrayed at the time, that was actually a really dark time for you. And when he came crawling back to you, you were totally walled off. Which you should have been, because he burned you.
And then you had CS and learned what it was like to be around a mentally unstable person. Arguing and her putting you down all the time. And, you showed us the picture of what you came back to. How could you possibly trust that?
So again, maybe my memory is faulty, but I feel like I'm pretty much in the right here. I think you have a good thing going, but all of your instincts are looking for that one moment where she will backstab you. And I hate to say it, but in all relationships there will be that moment where you feel fucked over. You just gotta work it out.
It's easier for you to go bang Philipinos because that shit is impersonal. No ties, no need to be close to anyone. I get it.
I think that what you have going for you is really good. Also for the millionth time, research shows that if someone with BPD can trust someone for 2 years, the condition gets a lot better. You're sitting there chilling with her smoking non-nicotine banana vapes. Like man...enjoy what you have. And in my opinion, don't let her whore herself out over this South America shit. She's following what you tell her to do. You're the one in control here, you have to be the man.
