My ex cheated and robbed me/but I gave him herpes

I was dating a guy for three years. He was so nice and he surprised me with gifts and he was the best at first. We loved each other a lot, well atleast I know I did. I found out later in the relationship that I had an std…called herpes. I passed it to him unknowingly. Well, at the time I found out I didn’t tell him. But I later did. He forgave me and still loved me regardless. The guy would bring it up when we got in arguments. But for the most part he never brought it up and still loved me. Later on in the relationship he started to cheat and stay gone for days. So, he eventually went to jail for selling drugs and I left him, only because he had moved in with a white girl two weeks before he had to turn his self in to the police. A year later he got out of jail, I was single and going through some problems…and he called. Of course he came to see me with money in hand and great sex. So I fell into his arms again. .because I was staying with a friend and lonely. So, we stayed in a hotel for like a month. A month later we got a condo.and I moved all my furniture in out of storage. So, we ended up breaking up, over something so small,like a month later. It was just an excuse for him to leave. Well he moved out. A few days later, I was arrested and locked up for 15days in a southern races town..for violating probation..it was for unpaid traffic tickets from a car accident something so small. I called him thinking he would help me. But instead, he came back to our house and had sex with a girl in our bed. Never came to see me..never put money on the books or nothing. So, I got out of jail came home and my house was emptied. I was devastated. There was a porno left in the dvd player all my pic’s where stuffed in a near by closet.my 6,000.00 bedroom set I paid cash for was gone..I paid cash for everything in the house. Well I got him arrested for felony theft my taking …and he served 18 months in jail..he has to do 3 years probation and pay me restitution. My ex just got out of jail and im in nursing school to be an rn, I’ve been so happy and at peace without him..I know that I hurt him in the ultimate way so I feel like I owe him my life or something. Like I should always give him a chance because I gave him something he can never get rid of. I was got herpes and I’ve only been in three relations and I’ve never been a wild woman..I only have sex with guys I date. Im very picky…so why did this happen to me…but now I feel that he called me and it brought all the pain back. He told me he is living with a girl…just to hurt me I believe…and why do I care??? Please help should I move on…or should I try to work things out with him?? He is like finish school and come get your man. I want him.but I know he will never be honest …or faithful..and he won’t stop selling drugs…im tired of him…???
