<human>: Give me the gist of the text in a nutshell

Hi /r/relationship
I'm (M20) currently in a relationship withmy girlfriend (F19) for two years now. For the first year, things were going well. We've made amazing expierence but currently, she just seems to get mad at everuthing.

For example: I promised my some friends to go bowling today. But she was going to chil with a friend of hers but for some reason, they are not going to chill anymore. So she is home alone now and she is just bored now. So she was getting mad at me because she wanted me to cancel my bowling night with my friends so I can chil with her. So at first I am not willing to do that but then she keeps saying that I'm not there for her when she needed me which in my eyes is complete bullshit.

She also getting mad at me for stupid things like the decisions I made, while she isn't involved at any decision like. While I don't get mad at any, in my eyes, stupid actions she make. I mean it's still her life and I respect every decision she made while she don't respect my decisions.
<bot>: She wants me to cancel my night with my friends, and if I don't, she said I'm not there for her like wtf
