Three years ago, I met a guy through friends who immediately started flirting with me. I was 17 and he was about 21 – four years older. We clicked and started going out sometimes and texting. He told me he had a girlfriend, so we kind of stopped seeing each other (nothing had happened), plus I was going to leave for a whole year. Then, one day before I left, he invited me over. He told me he liked me but … the girlfriend. And then he kissed me. He also said he would have had sex with me if I wasn’t so young. I simply told him I didn’t want to because he had a girlfriend.

During these three years apart, he never really left. He texted me sometimes, and when I dated a friend of his, he would make annoyed comments. Once, he video-called me on New Year’s Eve to say that he liked my perfume and that he wanted to kiss me – all while he was still with this girlfriend.

Then this year he called me and told me he broke up with her. So of course I was excited because it would mean a summer with him (even if just that, because we live in two different countries now). We went out and just talked for three hours. The third night out, we had sex. Then a week after, we went out with friends and then had sex again. He was already saying stuff like, “Let’s go here this summer,” or “You should consider this uni in *place where he studies*,” and “Let’s do an exchange; you come visit me and then we go visit you.”

But since our last night together, it’s been almost three weeks and I have not heard from him. I don’t know what happened. I know he’s not a good person because he cheated on his girlfriend so many times, but the ending still bothers me.

– What happened?
