re: Girlfriend is furious that I'm not attending her best friends gender reveal tomorrow.

Think about it like this. If you were a soldier and you had to go to war and she was getting pissy about you having to go to war instead of go to her dumb arse friends gender reveal party, how do you think she would feel if you decided to desert from your duty to please her and do what she wants you to do? Do you think she would honestly respect you for that or actually resent you for it? Obviously she would resent you for being a cuck arse bitch. It’s the same situation. You have professional duties and responsibilities that come before her. That’s called being a man. If she wants a pet accessory to take to her homo arse social events she doesn’t want a man.
