Would this alter how he feels about the girl to the extent he would actually break up?

I think a good amount of breakups happen for this reason, I've had to reassure some friends in the past because they didn't feel they deserved their partners.
The insecurity chips away at them and all you can really do with then I'd reassure them that you're not in a relationship for any reason other than that you love them, and that that's enough for you.

Yes and no. I've had a guy tell me this before, and it seems like a "It's not you it's me" type of line that isn't telling the whole story. But depression and addiction can definitely make someone lose interest in a relationship, and feeling bad about himself could have been his final push to end it. Just whatever you do, don't become wrapped up in trying to save him or salvage the relationship. You can be kind, but move on and don't let him make you feel guilty.
