That's a tough situation. You have every right to be jealous. My boyfriend has a group of girls that he hangs out with a ton, but they never invite me. So obviously that would cause a lot of jealousy on my end because he's staying late at some girls house with a bunch of other girls. But back to you, just wanted to show I could relate somehow. I think you should let him know how your feeling, but also be a detective yourself and spend a lot of time over there with him and her. If you sense or see anything going on, confront him but be subtle. Boys are stupid and can take that crap the wrong way really quickly. Hope this helps :)
