<human>: Can you give me the gist of the text in a nutshell?

We'd been together for a few months, friends for years before that and I was under the impression that everything was going swimmingly. We always had fun together, had great chemistry and I was so surprised at how comfortable we were around each other in such a short space of time.

Then the other night I thought I'd check in to see how he's feeling with everything when he told me that he's not happy. He admitted that he's been feeling depressed for the last couple of years and lately he's not been coping and has decided to see someone about it. He also said that he doesn't feel like he can be in a relationship until he's sorted himself out. He said he was scared that he would hurt me because he thinks that I like him more than he likes me but on the other hand, he also said that he's been happy with me and has had a lot of fun.

The whole time he was apologising saying he never meant to hurt me and that I'd done nothing wrong but that he felt like he needed to simplify things.

I can appreciate that he might be feeling stressed out about things and that getting help is a great idea but I'm so upset because he never even mentioned it to me and I would much rather be there to support him in any way I can as opposed to just having to exit his life altogether.

I'm not really sure where to go from here. I have told him that I am here to listen if he ever wants to talk. I don't want to contact him too much because that seems like it would just add more stress for him but I'm really hurting and I feel so confused about what I should do.
Part of me is scared that he just doesn't like me anymore and this is his way of letting me down gently. But if not, then I feel like I should fight for him somehow. I just don't know how.
<bot>: Relationship with bf was going great, out of the blue he broke up with me because he's depressed and doesn't feel like he can be in a relationship right now. Not sure what to do.
