<human>: We've been together for a little over 6 months and I'm starting to realise that we just don't have that much in common. This is mostly regarding our interests, and has caused many long awkward conversation pauses due to neither of us having anything to talk about.

Additionally, things that I used to find endearing in him are just becoming annoying. When I go on a mini-rant about something important to me he says something "finished yet?" when I've stopped. I feel like I'm trying to listen to him about his interests but he doesn't about mine.

The problem; he's really in love with me. He's had several relationships in the past and all of them have broken up with him. I'm his first gf after a 2-year break of depression. And I'm going to have to see him still once a month because of a group we're in.

How do I break up with him gently? Are these legitimate grounds for a break-up? Can we still be friends without things being awkward? I don't want to hurt him.

Can you summarize the given text in a few sentences?
<bot>: Don't have enough in common, endearing attributes are now annoying, he really loves me and I don't want to hurt him. What do I do?
