Well, if it's your girlfriend you're talking about. Maybe she's lonely. Have you been giving her enough attention? If not, talk to her. Maybe she is just having second thoughts about your relationship.
You should talk to your girlfriend about it. Talk to her about how it makes you feel when you see her flirting with other guys.
Maybe she was raised in an environment with mostly guys and they are who she's more comfortable to talk with...or maybe she's a flirt....
talk to her about it, tell her you are not fine with it and it hurts you. she will understand then
Girls are allowed to talk to other guys. If you are in a relationship you need to trust your girlfriend or prospective girlfriend and realize that if she likes you she isn't thinking about leaving you for other guys. She may have guy friends. That's acceptable.
A pretty girl who is funny and interesting to talk to.
Talk to her, let her know how her actions are affecting you. If she understands she will change.
Just be totally honest with her. She'll appreciate that and at the same time you can tell her that you wish you guys talked more together. She'll love that, girls normally go for guys who wanna talk things out and talk about their feelings, you know- the sensetive guys!
Go to an internet chatroom or talk to a guy who has a girlfriend and is dedicated?
Some guys who have a girlfriend prefer hanging out with their girlfriend depending on their age. Other's prefer their friends and may not have a girlfriend.
If you guys already broke up, then you cant really do anything about it. Sorry.
Maybe it's a reason to talk to you, maybe it's for his girlfriend. You need to ask him about it.
I would say that it depends on your relationship. Why did you guys separate in the first place? How long were you together? And how is your relationhip now? Do you guys still talk?
