Why does my friend always hate on men?

So im considering cutting a friend of mine off because im getting tired of her drama. So she will go out with a guy on a date then come back and have these horror stories about how all men suck etc. This last date really pissed me off, she literally said " I didn't want to give him my number but I did, I didn't want to go on the date but I did" and then the guy gets mad at her cause she's acting like a b**ch on the date and she gets on her social talking about him, why does she even go if "she didn't want to go".
