It's either yes or no

My friend is having major guy issues with her boyfriend. He's leaving to go to Colorado with his mom and the last night that she was in town boy didn't even invite my friend to dinner with them. He has been neglecting her, not to sound like a puppy or anything, but has his priotities all wrong. He has been wanting to hangout with his male roomate more than his beautiful girlfriend, I think he's gay. So my friend made a propasition to him, while he's away they shouldn't talk or anything and he should think about what he wants from their relationship, the man that would want to be wit her would have said no I love you and I want to be with you, but his response was alright I will and you do the same. How can someone just say that after begging for this girl back after 6 years? Why do men do that? Can't you men ever make up your minds?
