Me and my boy friend have been together for about 3 and 1/2 years. Hes 20 ans I'm 21. Over the last year we havent had terrible problems but we have had our momments of trouble. About a week ago I was checking email on his account because I also use it for myself. He gave me the password. While there I read a email from some girl that was saying how she enjoyed their date the other night especially the way it ended. Also there was more stuff like mention of phone calls and details that seemed to real. Since that email there has been about 5 or 6 others with more "I love yous" and details that make it sound like he has been cheating on me for the last 3 months. He denies all of it. Says that someone is messing with us. He even emails her back telling her that she is ruining his life ect. I have broke up with him for now cause I dont know what to believe. What do I do?
