boyfriend help

Hi, I don't post on here much but I need help. Men!!!!!!!!!! I have been with this spanish dude for 5 years. And I was 260 lbs. the whole time. Well about 1 year and 3 months ago he was acting stupid. I caught him cheating on me. Well being fat and ugly. I cried and cried and begged him to come back to me. Well he said we could still be friends. When we are together we are like dogs in heat. I am down to 115 lbs. now so the sex is great. He tells me he loves me everyday. I don't understand how he could love me and still have her. He said he don't love her. She lives in the same town as him. I am 45 mins. away. Well I don't know what hit me last night. But I was looking at myself. I thought I am not a ugly fat woman anymore. I think I deserve to be treated better than this crap. So after 1 year and 3 months I told him last night he had to choose. I was tired of him being with 2 women. And he don't want me to date so I haven't...........He said " I can't even see her at all" I said a bad word and nooooooooooooooo!!!!!!!!! I think I would rather be by myself lonely than to be treated like this. I feel like he only wants sex. That is all we do when he is with me. I want to be taken out for dinner or go somewhere. My head is going in several directions. I just don't know if I can get another boyfriend. Please any advice. I went through a bad divorce 6 years ago. Caught him with his boss lady at a motel. Men just don't do me right. God I am sorry for venting and being confused for what to do. Any advice will help. ( oh yeah she is a big woman ) I think he is going to let me know today what he chooses to do. And I think he will still choose both of us. Amy
