A safe haven
when he stop hanging around you
either impress him or brake up with him
Bad sign
If your boyfriend overreacts because you're hanging around another boy more than him, tell him that you're just friends and you can spend more time with him, but you won't give up your friends.
Hang up or speak up.
yeah.... sounds odd.
if you is not hanging around you as much, not going on many dates as much, or are you his center of his world
Stop hanging out with him.
This really depends why she is calling you. If she is calling to talk to you about your interests and hanging out, she probably is interested. If she is calling you to find out who keeps calling her number and hanging up, then probably not.
whatever you do don't make him pick between you, his girlfriend, and his friends who hapen to be girls without finding out if he is actually cheating on you or not. if he is cheating on you though dump him immediately!
tell him straight up you wanna do more stuff together
