Hes flirting with me while holding her?....help?

My friends boyfriend is really flirty towards a lot of girls. But lately he has been even more flirty only towards me. He told my friend that I am one of his good friends when we barely hang out and now everytime he sees me he whispers my name into my ear or pokes/annoys me. Yesterday he was playing footsies with me while holding his girlfriend in his arms and when she would look away he would do it. I used to think he was scum for doing that to her even if hes jus joking and teasing people. I dont respond at all or flirt back because I dont wanna get into that. Im slowly starting to fall into his trap and I dont want to. I dont wanna fall for him and I dont want my friend getting hurt but we arent very close and she doesnt see what hes doing as bad. What should I do?

Wow, this guy sound like a real jerk. For me I think the best thing to do is to tell him straight out. U should talk to him, and tell him to stop bothering U. & U should try to stop urself from falling into his trap, cuz that's just what he wanted.

"Im slowly starting to fall into his trap and I dont want to."

If you don't want to, don't. What is there to fall into? A relationship with someone who would treat one of your friends like dirt? Use your words and tell him to stop, plain and simple.

She's your friend.. and if he's doing this to your friend and he leaves her for you.. he's just going to do the same thing to you and you would have lost a friend for a complete jerk

Hun, do don't this. DO NOT do this. She is your friend. She trusts you. She thinks that everything is going great and that nothing is going on between you two. Prove her right. If you care about her AT ALL, you will leave him alone.

This kind of situation terrorizes people. Ignore him. Stay away from him. She had him first.
