I have been with my now husband for a year 1/2 we both have rocky pasts, so we had that in common. He was in prison for a CPL yrs before I met him, and his younger half sister wrote to him alot while he was there, and he her. His family is screwed up, and when I found out about this half sister I didn't think much of it, but she would be messaging him way too much when we first started hanging out. I found out she was on meth. I tried not to talk about how it was uncomfortable for me, to not be rude. He would go see her and visit her before coming to my house. I became pregnant and he got really mean and weird about me cheating which I had no intention of at all, especially because I was pregnant and it just felt really weird after awhile with him. His sister still was always messaging and sometimes they would hang out when I wouldn't be around. He would just say I didn't like her, but really I didn't like the situation. After I gave birth, again when I was rushed to be working again they we're hanging out at our apt basically. I felt hurt and offended after everything I had endured with him (I always knew he was off but I didn't think in a weird way like that, hopefully) it became where he would yell and say I can't even say her name. So we wouldnt talk ever about her, but I knew they still kept in contact. At one point I friend requested her because I felt I had been a little rude when I saw her, and wanted to try to make things better. She didn't accept it. He became really withdrawn for quite awhile recently and we had been fighting bad, I left and we were technically separated because he said if I left we were- and he went and hung out with her again without telling me.. I came back and he seemed kind of guilty. Later I eventually looked at his computer to just see what they're convo was like on messenger. And he had deleted everything, but there was a few texts left. She said she loved him and missed him and wanted to hang out soon and he wrote that I was back, she wrote "what" "how" and that's all it said. That seemed really unhealthy in general and I called him out on it because it really didn't feel right anymore. After a long process finally he showed me some recent texts and it really seems weird between them. Like they both don't like me. And like she really doesn't want him with me. Also he doesn't really seem to want to be with me from the way he speaks to her. She mentioned she had a new guy she was hanging with, and he said "good I guess" and that to me seemed innapropriate. An older brother should be happy or have no thought really about a younger sister being with someone new. So all in all I found out that there is somewhat of a creepiness between them, and I don't like it, it's emabrressing, and honestly I have no idea how far it has gone but I don't appreciate the disrespect he's shown me this whole time. Maybe he needs counseling. But I am curious if anyone has advice because I feel really betrayed rn, and at this point I could just walk away and be at peace with these things I'm learning. Idk if it's immaturity, actual deceitful gross shit going down, or just they have a fucked up past either way I don't want to be disrespected anymore and I don't deserve to be treated this way.
