my boyfriend cheated on me with his ex should i take him back
I have been with my boyfriend for a little over a year. Things were great until 3 months ago. He stopped feeling for sex. Saying that he was stressed at work and other personal stuff. Before we met he had recently out of a 13year relationship. But the girl was unfaithfull to him and they separated. They remained friends and I always suspected that they were still messing around. But he denied it all. He always keeps his phone locked but about a week ago he fell asleep and forgot to lock the phone. So I went through his messages and saw that his ex used to spend nights by him and he by her. It also looked like she had a man but he was doggin behind her. I didn't see anything about sex but its clear if they are sleeping over by each other sex was taking place. I confronted him about it and he began crying and saying hw sorry he was. But he swears that they never had sex. Of course I don't believe him. They say everyone deserves a second chance and he has always been good to me. But I am thinking that this isn't any random girl that he can just forget about. Its clear that he still has love for this ex. So I really don't know what to do. He is begging and pleading for me to give him another chance. I already said no but sumwhere deep inside I am having second thoughts. What would u advise??
