My bf don't know what to do with him

I had bf before I get married to my husband he was always treading me as princess he wasn't in good looking so people always were telling me how ugly he is and we don't match but I never saw him ugly as they said I stayed with him for almost two years but after that I had to leave the country then in new place I meet my husband and he asked me for marry before I say yes I asked my bf to come over and get engaged or something but her fused to do that and he tried to find many courses so we left each other then after 8 months I got married after I got married I went back there for visit and I saw my old bf we talked and we spent some time together at that time I felt that I only love my husband and saw him as ugly as people told me and I even felt sorry for the time I spent with him before and I was so happy to have my husband in my life not him but this days I'm kind missing him I don't know why I even sometimes wish if the time go back and spent time with him I don't know why sometimes I think maybe because my husband is not romantic as him or what? And what should I do call him, talk to him or send him email or something? But at the same time if I did that I will feel I'm cheating on my husband I don't know what to do I  just missing him missing the time which we were spending together
