Didn't love him

When he gave me the engagement ring I knew we would never get married, he didn't deserve me.. and he knew it also.. but the sex was great.. I never loved him, I loved sexing him.. 3 months later I knew he was cheating but I never said anything because I didn't care.. I was cheating too.. but when the sex went downhill I finally put him out... I know of the girl he is with now.. she loves him and he still begs me to take him back... I let him beg because it makes me feel wanted..
