Not sure if I'm being crazy?

I'm sort of thinking about breaking up with my boyfriend now after we talked last night.

He is a great boyfriend and I love him, but I suddenly have a lot of doubts about why I'm here.

I usually prefer being single, but I have a big heart and am deep down a romantic so I always end up dating someone in a committed way. I live with him, but would be able to leave, or even stay.

He's depressed and deals with emotional issues and I'm absolutely concerned about him, but it makes him sad when im sad, and I'm sad a lot because I also have issues.

Then, we're having less sex and it makes me feel confused honestly. It seems like we both want to, but are being polite and weird about initiating??

He also got divorced this year and said he has no one to talk about with it, and I told him he could talk to me, but he's afraid I'll get jealous. But I am very understanding about that stuff.

At the same time, maybe he's right because I feel like, maybe I jumped into this relationship way too early, and maybe I was right when I didn't plan to commit to this.

He has abandonment issues, and I am not the best choice for him, perhaps. I warned him, but he really liked me. I really like him too, as much as I tried not to.

Im not mad at him or even unhappy, im just, not sure I belong in this equation all of the sudden.

Thank you for any advice.
