Advice on cheaters?

My fiance cheated on me 2 times and I always thought that he would change, but he never did. I don’t know what to do cause we just got our own apartment wich is under his name and not mine. I know I made a big mistake, even my parents told me but I never wanted to listen to them cause I really thought I loved him. But now I know if he keeps on hurting me I am going to keep on hating life. I don’t want to kill myself cause I know thats not answer for everything. I helped him with his bills cause I thought he would think of me as a specail person for helping him but I guess I was wrong. He sais I am his only one but I know he will keep on messing around with other girls behind my back like he has for the past 8 years. I know that he loves me but if he really loved me he would never cheat on me. I tell myself what would I do without him. I know I will try really hard to get over him cause I have to be strong. Diana I will always love myself cause thats the only way to get through life.
