So this guy I like is 17 and I'm 18. We get along well and he teases me and I do it back and we have fun in class. I usually see him staring at me and he usually says hi to me and stuff and always smiles. Well I messages him finally this weekend about class and we talked for a while about different things and that was that. Then ever since then he doesn't try to engage with me as much, avoids looking at me in the eyes when talking to me and is almost avoiding MW and I dotn get it. My friend that knows him said he distances himself sometimes and is complicated with emotions and people. I'm not sure what to do cuz now he talks to other girls easily and not me anymore and he used to usually only try to talk to me. What do I do?
