I 21f live with my ex 20m and we’ve been broken up for about two months now. About a month or so after he broke up with me he tells me he’s bringing a friend over, I already had my suspicions when he said a girls name but ignored it. Then when she came over they went straight to his room and then I had fully accepted the idea. I started downloading dating apps because I felt like I had to move on because he did. And as guilty as I feel about it we had breakup sex a week before he brought her over.

Like an hour or so of her being her I heard panting noises and immediately connected the dots and texted him asking if he was really doing this. He had previously said when we broke up that he wouldn’t bring anyone over and have sex with them so he had overstepped my boundaries. He somehow didn’t understand that’s what I was saying the first time and later when I heard it happening again I sent another text saying really bud? But he still hadn’t gotten the hint until I was taking a walk and he was out there that I had confronted him about it. He claimed to not understand what I meant about those texts and said he didn’t remember saying he wouldn’t bring anyone over for sex.

Today he had her over again and I was gone most of the time until I came home tonight and everything was fine, I took a shower, and laid in bed. Until I heard it again, I sent another text asking why he was doing it again since he knows that it makes me want to end my life having to hear it, and that I had mentioned to him several times before she came that I didn’t want him to have sex with her in the apartment again. He tried to tell me he wasn’t until I pointed out the condom I saw in the trash. I did the irresponsible thing and started drinking and got the liquid courage to tell him that I didn’t want her here anymore since she was staying the night. He immediately said that it wouldn’t be a problem anymore because they were going to sleep but I couldn’t stand her being here in the apartment so I kept pushing her to take her home. She didn’t want to go home because it was late and she didn’t want to drive.

He said he was half asleep but I couldn’t accept that as an excuse since one of the reasons he claimed he had broken up with me was because of a night I couldn’t help him when his scooter broke down because I couldn’t keep my eyes open. I was still drinking and am still under the influence so I don’t trust my judgement. I ended up threatening to call someone to get her out because I couldn’t stand her being here any longer. I didn’t have anyone to call and was an empty threat but I immediately regretted saying so. Not that he knows that. They left and he said he would figure something out after I told them both to leave and now I just feel like shit. She lives an hour away and I’ve never met her but I work with both of them so I don’t imagine this going well for me and just want to know if I was an asshole for what I did.

Just to add to what I told him I also told him that he was becoming like his mother in the way that he was making everyone miserable. This all happened over text messages so I didn’t approach them directly.
