I'm going to break up with my girlfriend at her birthday party
Why break up with her at her birthday party?
It's an easy decision for me. I'm just doing what's convenient.
You should never break up with people on their birthday. This could really hurt her.
I think if I do it this way then she won't try to stop me from breaking up with her.
Probably not, because it's a pretty awful thing to do. It's OK if you want to end the relationship, but don't ruin her special day in the process. How would you feel if somebody broke up with you on your birthday?
