So complicated history, lived with my biological grandma all my life till her and my mum died a year apart. Then I was given to an aunt and uncle (biological) who had 5 kids, I was the eldest. I became the surrogate mum, raised the youngest from birth, gave them all my money while they mentally and physically abused me, falling into depression. I met my ex, who is also my brother out of choice because he and his father saved me from there, giving me a home and a true family, when my biological family kicked me out and disowned me and also supported me when I was raped by a workmate 6 months after being kicked out.
Currently he has a gf, who he has explained the situation to about us being ex’s but realising we were more like siblings/best friends, so chose to be family instead. She still sees me as the ex. And I’ve been trying very hard to make things work with her.
The other night we went out, and me and her were being girls and having a conversation with some guys while he talked to another friend. Then for some reason he pulls me aside, not her, and has a go at me, saying to not be so foolish, and that I should be in a relationship like him. I tried to explain I wasn’t like him, and get him to go back in so we could find his gf cause he had left her in the bar. Once I got that fight settled, we left the bar, and something happened between her and him and he walked off. I chased him even though he tried to push me away, and he broke down crying about his situation. I let his gf take care of him while I stood by to keep them safe so it didn’t seem like I was making him choose, but he ended up wanting me to comfort him anyway. I calmed him down and we made our way to bus to head home. Just as we got on and were waiting for it to leave, he started to have a go again saying we were making him choose between us while the whole time I have always pushed him to choose her, minus a few family times. Angry I told him I would wait for the next bus, cause I knew my way around and they didn’t. But then he ended up getting off the bus and left his gf there alone where no idea where she had to go. The girl he says is the one and is crazy mad in love with.
Can someone offer advice as to why he would have done this? He broke up with me, resolved all his feelings before I did that we were just siblings now and that we weren’t really in love. I don’t understand why he would do that?
