<human>: I am with my gf in a distant relationship for 6 months now. But I see a pattern that when she goes and meets her bf at her hometown she calls me and at the beginning asks if I'm ok and if something is wrong I say ok and that's it. Then she calls later when out and starts trying to start a fight with me without any reason and she acts all bitchy and bossy cause I tell her to drink responsibly at which I say that I'm sorry for carrying for her and she says that I don't trust her and I think she is a whore or something. I tell her that I don't believe that and I'm sorry and that I will stop being so possesive but I hope that my worries won't turn right at some point.
She hangs the phone and I'm like wtf?

I know it was a bit jerky what I said but I'm always honest with her as I really do care and wanna stay with her but the way she acts makes me furious like she is intentionally trying to provoke me. A while back I overheard her talking with her cousin that she will break up with me after Easter. The thing is that she also booked tickets to Budapest for us and that she tells me all the time that she loves me...

Please help me and give me some tips on what can I do!

Could you distill the essence of the text into 1-3 sentences?
