AITAH for telling my mate to shut up about his girlfriend?

Recently my mate keeps complaining about his girlfriend, he’s been with this girl for like a year now but only now has he started consistently having issues with her that he brings up. It feels like every time I see him he brings her up at least a few times and I wanna help him but it does get to a point where it’s frustrating. He doesn’t seem to take my advice even when he says he does so it’s not that I haven’t tried.

when he brings her up i just try to listen but not feed into it more however today we were hanging out and he brought up his girlfriend and about how she talks back and has attitude and I said just shut up about (gf’s name), I get you’re having problems with her but I don’t want to hear it anymore.

He responded saying jesus okay I was just talking. I argued back a bit because I wanted to get my point across, I said you keep talking about her so at this point you should just break it with her or just figure it out on your own.

He argued saying I’m deeping it too much and he just wanted something to talk about. We don’t usually argue and i was frustrated with him so it got awkward and he continued on his computer. We were going to do something but we didn’t. I think I wasn’t the asshole here but I don’t know for certain, I made things awkward and I could just smile and nod but I didn’t

Oh by the way we are both male 20, sorry if some parts are worded in a weird way i’m ukrainian.
