OK so one of my bestfriends has been going out with this guy for a month now and there's this guy right down the road that wants to hang out with her. And she doesn't want to so her boyfriend wrong by hanging out with him because she wants to stay faithful to him but at the same time she does want to hang out with other guys but she's afraid it might hurt him. She wants to hang out with this guy but she doesn't want her boyfriend to get mad at her.then she said one time she was texting this guy and her boyfriend kept calling and she kept ignoring the calls because she wanted to keep texting that guy but no she feels bad about it.what should I tell her she should do?

Well there's nothing wrong with a girl hanging out with a guy, but if she feels some guilt about it, then that may be telling her something.

If she's hanging out with a guy such as going to lunch with him or something like the sort, there's nothing wrong with it. A dinner and a movie... with him alone... may be a bit of a problem. But it really depends on the boyfriend. Have her talk to him about what he feels comfortable with.
