OK so trust me I already know what I've done is wrong so if you are just going to harp on me for that then please don't comment- I need a real answer.

So this guy and I have been texting and sexting for over a year now on and off... let me just say we were friends first and every time we would be around each other we would flirt. I stopped texting him one time and then the next time he stopped talking to me - just a text here and there between us but every time we come back to each other (he's the one who comes back every time) he says that he misses me and is always telling me how beautiful I am. We do talk about normal things too not just sex. So about 2 months ago he found out his wife was pregnant. That was one of the times we had just started talking again and then when I found that out I stopped talking to him and he stopped talking to me other than when we see each other out we would be friendly and have casual conversation. So about now his wife is 5 months along - and a couple weeks ago he would text me and just see how I was and say he missed me and that was about it and then last week he started texting me every day. I felt like I was finally over him and needed to move on and be fair to my husband and OF COURSE to his wife... what I want to know is why does he keep coming back (other than the whole reason of his wife being prego and he's prob not getting much action) I mean like all the times before- if he's not really interested in having sex with me ever or leaving his spouse why does he keep coming back to me. I feel like he makes this harder for me when I'm trying to do the right thing. I mean is it an ego thing? I'm just so confused!
