So I've been friends with this guy for 3 years (we are classmates) and we've never been "just friends" but also nothing more than that. He introduces me sometimes as his "wife" (playfuly) and tells me I'm wife material, but at the same time he tells me about the amount of girls he's kissed before. Once at a party, where girls invited, I brought a friend as my partner and he was also invited by another girl. He kept dancing in the same circle where I was dancing and he didn't care I was dancing with my partner, he started dancing with me when couple songs started playing. But in the next party, were boys invited, he invited a girl he had history with and was flirting a lot with her through the night but I acted as if it didn't matter and stayed with my partner (friend) since he invited me. I am really confused as to what should I do. Thank you!
