Is this cheating?

My girlfriend of about 2 years had to move to the westcoast because her dad got a job there last summer. So far, it's been a 4 month long distance relationship.

Lately, I've been acting like an ****** to my girlfriend because she's been spending alot of time with one of her close guy friend and i voiced my displeasure to her. We got into a big fight last thursday and I said things I shouldn't have said. Basically, she thought we had broken up because I did not call her and wished her luck on her exam and because of the things i said. She went out with her friends including this guy for dinner after her exam, and when this guy dropped her off, they pecked each other on the lips. I don't know who went in for it, but by the way she was saying she doesn't know, I think it was her. She told me this today, and I was upset, and I didn't know what to say and yelled at her, and we both broke down and had a ball. She also told me she had feelings for him, which i suspected. I was insecure about her spending alot of time with this guy because when we were physically together (1.5 hours apart), she would continue relationships with guys that are obviously hitting on her with the intent of getting in a relationship with her.

She said she would cut ties with this fellow, but I have my doubts because she said she would sort it out with him tomorrow. Mind you, this guy told her to break up with me, and that she deserved better after she confided in him about our problems.

I can't stop thinking about it, and I don't know what to do. She told me she had feelings for him because he makes her feel special but she also told me she loves me, and only likes him.
