We have mutual friend and we are friends. We have hanged out but only in a group setting. My friends say he is interested in me because he dresses up for me and is always happy to see me. But I don't know if he is interested in me or is just being nice. He playfully mentions that he would love to go out with me but then he always say "jk" so I don't know if to take it seriously or not. I am confused? Should I just wait until he makes a move or just move on?
