I want to break up with my gf because she doesn't want to come visit me
Why won't she visit you?
She refuses to leave her friends.
You shouldn't break up with your partner because they don't see you. Tell your partner that you'd like to spend more time together. You should give them a chance to meet your needs.
I will break up with her since she's a bitch.
It just sounds like you two need to sit down and talk about the subject as you don't seem to be on the same page. I'm sure if you did that then you could come to an agreement about visiting each other.
