So I'm 15 and never kissed or done ANYTHING with anyone till recently. We don't have feelings for each other (that I know of) and we made out and stuff but not many people know and if they did they would get mad because they don't think he's a good guy, but he's really nice to me, and his ex for 1 year got upset and made me feel bad. Should I feel bad even though he's not dating anyone are dated anyone for a while?
