Relationship advice

My boyfriend and I have been dating for 10 months and I don’t know if I want to be with him anymore. But I’ve never broken up with anyone before. He treats me right but I just don’t feel the same as I did when we first started dating. He has anxiety issues and I care about him a lot. I don’t want to hurt him. I don’t know what to do. I think about leaving him but then I remember all the good times we’ve had. I just think I’m a bitch for leaving him since he’s never done me wrong. I just don’t feel the connection anymore but I know he loves me and I would crush him if I left. Any advice would help!
