So I've been seeing this girl. Everything was going good but after 6 months I've been cheated on 3 times with the same guy. My girlfriend literary will pick a fight so we break up and then get back with me every 2 months. I can't get a girl besides her and I know she's just using me. I found out she cheated on me the first time and I took her back just to find a picture a hung guy in a hotel room. I asked her did she take that pic but she said she didn't. Well why would she have that picture saved in her email? She sent an email of that picture to herself. I seen the same guy in her apartment complexe 10 times. She says she doesn't know him but why does she have that pic?
