I'm mad at a friend because her new boyfriend doesn't want her talking to other guys
Is it ok with her boyfriend if she talks to other girls?
No, she wants to still talk to other guys
It doesnt seem right for her boyfriend to restrict her from who she can talk to. She should be able to talk to whomever she wants whether she is in  relationship or not.
Friends are a different story. I just don't like her being mean too.
That makes sense. That does not sound like a very good relationship if she has to be restricted from seeing certain people. Hopefully that changes for her.
