There's the guy I've known for 3yrs that has been asking me out but I was already in a relationship and I never really liked him for relationship, just as friends. So he continued, flirting with me and all that. Sometimes when I go to his house, he's all over me, touching me, kissing and still be asking me. I told him, I know he's playing around with girls and not ready for a committed relationship, that he just wants to be benefitting but anyways, he had a party and invited us, so there was a particular girl, he kept talking to at the party, but no need since I'm not interested in him that way.
Today I saw him and the same girl together but this is the person days ago, that was calling and upset because I did not come to his house over night to spend with him. I just want him to be honest with me, so I saw them, the girl saw me and waved, but he didn't see me. I told her to not say anything.
I don't know why I am a little upset, or not or do I have any reason to?
