I've been with a guy for five years. He has an ex wife and in the past year I found out that he has been sleeping with her as well. We lived together for four of these years until I found this out. I moved out and was heart broken. When I confronted him he said she was lying and he never slept with her. He text and rang me and I let him back in to my life and this past month I feel that he has just been using me. He tells me he loves me and wants me back yet then il not hear from him for days and then hel be all I'm sorry my heads up my bum and I don't mean to hurt you etc etc and I keep letting him do it. I feel so depressed and upset I cry every night can't sleep. I feel so alone I can't tell my parents about it as they hate him for what he has put me through so I don't want them to know I've been back with him for months.
