So my girlfriend of about a half a year cheated on me on Saturday night. She didn’t sleep with the guy, but I guess they made out and he tried sleeping with her by starting to take her pants off. She did stop him and said she couldn’t do it, because of me she says. She and I are about five years apart in age (18 and 23). Now I love this girl. I have very strong feelings for her and want to see us work. I am leaving for the military in about seven months and want nothing more then for us to be together. But I am having doubts because of her not so shiny past. She has been with 17 different guys since the age of 14. I trusted her word once that she would remain faithful. Should I give her another chance?
