Is it normal for a 28 yr old man to want to be with a 12 yr old girl??

I am 29 now...going thru a divorce I was married to this man for 10 years!! we started dating when I was 14, but he had showed me that he was interested in me when I was 12, I got pregnant when I was 11!! I was raped..by a boyfriend and I choose to have my child, I met this man he was my friends uncle, he had kissed me one day..and I thought oh my god, we messed around a little bit but no sex, about a year later we started talkin a little more, then one day he had me give him oral sex not something I enjoyed but dominance takes over..here and there we saw each other, then one day I was painting a new apartment for my mother and he came over we ended up having sex I was 14 he was 28...we ended up becoming serious although he had a bad drinking problem and drug problem...I wasnt into any of that..so we would fight alot, I ended up moving in with him when I was 17 and married him at 18...we had lots of problems, he treated me like his slave, as I have gotten older and now him and I have 2 girls, 6 and 4...I have grown wiser and stronger, I dont want my little girls growing up thinking its ok for a man to treat you like garbage or like you are nothing...I had goals to finish college but he didnt like that, he saw me as a house wife and mom and thats it, not as an educated woman with a respectful career, so last April I left him...our divorce has been very messy, I was left with nothing, no money he took all our belongings, and is giving me trouble with the kids, I have had no help from anyone, I tell myself over and over that he loved me when I was 14 but then I think about it and it seems so grose, having little girls and thinking about a 28 yr old man having sex with my daughter makes me sick to my stomache he has 1 of my daughters full time my 6 yr old, and now I have thoughts that OMG what if he has a thing with my daughter is that wrong of me to think that...its her dad??
