Think i messed up pretty bad...
So aafter my girlfriends graduation party, i was chilling at her house. She hands me her phone and goes to the bathroom. I always use her phone because she still has unlimited data, but today i was using it and a text came up.. It was from a guy ive had problems with before. It said "hey im sorry i missed your call last night ill call you after i get off work"
I didnt mention it for a while, but it finally got to me and i asked her about it. After a while she breaks down crying telling me i always f*** up her good days, every thing is about me, and other various phrases of that stuff.
Now i feel bad for ruining her day, help me out guys. Please.
Tl;dr gf got text from guy. She apparently called him for unknown reason. I ask her bout it. She rages, then cries. Lots. Now im asking for help on what to do.
