AITA for relying on my ex after the ER because he said he was free, only for him to reveal a date later?

My ex and I broke up a little over a month ago, but it wasn’t some big dramatic thing. We stayed friends, mostly because I literally don’t know anyone else here (I moved to his city when we were still together). He always said I was his best friend, and honestly he was mine too. It was a very smooth break up.

Anyway, on Friday I ended up in the ER for something I’d rather not get into. When they discharged me, I told him I didn’t want to be alone for the weekend. The meds they put me on knock me out and I wasn’t supposed to drive, and I don’t really have anyone else around.

Before I came over, I asked him straight up if he had any plans or dates or anything going on. I told him if he had stuff going on, it was fine and I’d just go home. He told me the only things he had were two hangouts with a mutual friend (one Saturday, one Sunday), and he invited me to come along. Otherwise he said he’d be home and I could stay the whole weekend.

So I went over Saturday. His Saturday plan fell through but it was fine, we just hung out. Sunday morning, his other plan fell through too. I told him we could go out so he didn’t feel like his weekend got wasted, and I even offered to pay to say thank you for letting me stay. He doesn’t really have many friends anymore because he lost a lot of them during/after his divorce.

In the middle of lunch, totally out of nowhere, he tells me he’s been talking to some guy for the past week and that this guy was actually supposed to come over that night… for drinks and to sleep over.

I was like… what?? If I had known he had a date or whatever, I would’ve stayed home. And I literally couldn’t drive because of my meds. It just felt like I got blindsided.

He apologized and said he’d cancel, but I told him he clearly wanted to go on the date and I didn’t want him canceling just because I happened to be there. After that he just kind of shut down and acted like he wanted me to leave. So we went back to his place, I grabbed my stuff, and left.

I texted him later telling him it wasn’t cool. He said he “helped me out” all weekend and he’s not going to stop living his life for me. I told him I wasn’t asking him to do that, I just wanted him to be honest before telling me to stay with him after I got out of the ER. Even as friends, you don’t kick out someone who needs someone because you planned a date.

For some background: this kind of thing was always a pattern. We were in an open relationship and hookups always seemed to be the priority for him. And earlier this week he invited me to his Thanksgiving dinner because he thought no one else would show up. I was also there for him through his whole divorce and all the loneliness that came with it.

Now he’s telling me he *does* prioritize me and that he has done everything he can. But he isn’t going to stop living his life for me.
