Hi, I don't know if I should feel happy about it, I have completely gotten over my ex?

but I am feeling as if now that I don't have ANY feelings for him, am I doing justice to him, though I really loved him( from the bottom of my heart) but he treated me really bad, I suffered from low self esteem cause of that relationship... I was really faithful and loyal to him but I was just another option to him and he cheated on me several times, I came to know about it and I broke up with him, but still after breakup I wanted to be with him and wanted to give him a second chance but I stopped myself from doing so because he was making a fool out of me and that was it, the recovery period was like going through hell, but now I am over him :D and I enjoy my work, enjoy meeting new people and I have never been this happy in that relationship
