My brother thinks that I'm a bad guy for not taking his girlfriend's side in his argument.

I mean after we confronted her, she told us that she's sorry. I told her that I'll forgive her when she learns to communicate. She was upset that he wanted to be with me instead of our family. Why can't she talk with him about it instead of being silent and take my space with my brother.<br><br>My brother told me that I'm a bad guy who takes his girlfriend's kindness for granted. Idk why. She said she's sorry. Why isn't he taking my side in this? I'm his brother. Why can't he see this from my perspective?
