What if I don't go overseas after my girlfriend's mother passed away?
Why aren't you going to support your gf?
Because I felt comfortable staying where I am. I am not motivated to travel.
You may not feel like traveling, but it is important to support your gf in her time of need with her mother's death. Put aside your laziness and go overseas to be with her.
I don't know why you think that I should do things for her just because she is sad. I am not her father.
You aren't her father, but you are supposed to be her boyfriend which means supporting her through tough times. If she wasn't willing to be there for you, would you be happy?
