It kind-of depends on the girl, and the boys she is hanging out with.
If your girl is chilling with your best mates, or with a few guys she's know for years then.... Don't freak out! She is just being herself, and trying to be as normal as possible around you.
But if its like a player at your school, or just some REALLY buff boys that she's know for a few days, weeks, months. Then you might want to be concerned. I mean don't be controlling, she might just want some time to breathe. But don't let her just go and ditch you. That's just wrong.
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.
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.
iF YOU SEE HER WITH OTHER GUYS WHOM SHE CLAIMS TO LIKE.
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.
he secretly goes out with the other guys girl
The only reason you would want your "girlfriend " to see other guys if you are seeing other girls. If you want her to date around, tell her you've been seeing other people.
NICE and non-jealous guys!!!

Do not worried about it. If you r not with her anymore. Or just tell her u r having dreams about her with other guys. Most girls will be true to their guys.
