TIFU by calling her another girls name in bed.

I'm 21M and my female friend is my roommate, let's call her Anne. We've been living togehter for about 6 months. Because of covid, she didn't find an apartment so I offered her to stay with me. It's just temporary and she's going to move out in a few months. I met a girl, and asked her out on a date, we had alot in common. A few weeks later, she told me that she doesn't want to date me, since she isn't okay with me living with another girl, and she doesn't want us to be this close. I could totally understand this but I've known Anne since I was 4 years old, it's not like I'm going to cut off this friendship because of a relationship. I told her that Anne was moving out in 3 months. But she still insisted that we're too close to eachother. So last evening we talked again and she told me that she's still insecure about this situation. I reassured her that, nothing is happening between me and Anne. Later on that evening we had sex and I accidentally called her ,,Anne" didn't even notice at first. She just looked me dead in the eye and jumped off the bed. She said that I was thinking about her the whole time we had sex, which isn't true lmao. I hate myself for laughing at situations, which aren't funny but serious. She put on her clothes and left, and I was still trying to contain my laughter. She blocked me on everything so I guess it's over. Honestly I do feel really bad for making her feel insecure, and laughing afterwards. I guess it izz what it izzz.🤷🏼‍♂️

TL;Dr The girl I was seeing wanted me to cut off the contact with my female friend, which I've known basically for my whole life. She was insecure and jealous the whole time. I accidentally called her my female friends name during intercourse and started laughing. She blockdd me on everything and I guess it's over .
