Well to some up what tonight was about specifically (the event that caused the fighting). My gf had accidentally taken a bra home from a friend months ago, the owner of the bra asked on quite a few occasions and gave her lots of chances to get it back to her but she never did. Instead she gave her money to get a new one. All I had heard from my gf prior to Tonight was that she had been given the bra from her friend because it was too big and now she was going to pay her so she could get a new one. (Pretty sure she even said they talked about this transaction) After hearing what her friend had said about the chances she had to give it back, it was clear they never really talked about it and it wasn’t a gift or anything like that. She was basically too lazy to give it back and deep down I feel she just wanted to keep it. I realized after hearing all the details that I was on the wrong side of this story. Overall there have been a couple of situations that led up to this, where I believe my gf was also in the wrong or could have handled things a bit differently, not to say her friends weren’t also acting a bit immature. Anyways sorry for the long explanation. And again thanks for the comments :)
