To add this person had it right. The good thing here is he was honest with you and not stringing you along. Its not selfish. Selfish would be staying in a relationship he didnt want to stay in.

After all, why would you want to force someone to be with you if they want to move on?

I had a girlfriend and she was angry at me bc i wouldnt move in with her. But i love living by myself. I dont want to share a bed with someone all the time. I like sleeping alone a lot of the time its just way more comfortable for me that way and she wasnt ok with that. And thats fine! Then i found someone who was okay with it.

You shouldnt shame him for doing what he thinks is best for him. Your perspective here is what you think would be best for him bc it would make you happy. But he’s done you a real solid here and was up front and honest and told you his feelings. Thats pretty rare among people at times, so once you get over the initial shock i have faith in the future youll be thankful he did this rather than stay in something he didnt want to.
