I met a guy in high school and we became really good friends. We then decided to date and after a while we decided to date exclusivly. We were juniors in high school. After about six months he cheated on me, he slept with my best friend after I found out I asked if he had cheated on me before and he said there was one other but they just made out. I decided to give him another chance we have been together since I felt like it made us stonger and things were amazing for a long time then he started going out with his friends a lot and just recently we broke up because one night he went with his friends to a bar and slept with another girl it has been three and a half years since the last time he did it we are not married yet but we have talked about it many times he wants me to take him back again and I really want to make this work because I love him so much but I am scared for our future do you think that this could really work or do you believe the old saying once a cheater always a cheater.
