I'm torn between two

I'm a 21 year old girl. My ex (who is 22) broke up with me about 7 months ago and we haven't really spoken since then. When he saw me face to face he cried and said he didn't want to do it but had to cause he loved me and I deserve better, I deserve someone who will be around 24/7. Seeing him cry I made a promise to come back after the 5 months he would be away and I would live my life in the mean time. But his bestfriends girlfriend told me that we wouldn't be together again so after batteling myself I started to see my work mate who is 34 and has 3 kids with his ex. Last thursday I caught the guy I'm seeing talking to other woman on the internet, these women he use to chat with on a regular baises before we got together, the content of thier chats is of a sexual nature with me finding that he was wwbcaming with them and sending photos of his private parts as well. When I confronted him he said he didn't know why he did it and says that he really is happy with me but I can't be sure. The problem here is that I'm not over my ex....I love them both and I don't know what to do I'm not sure if I love the man I'm seeing because of what has happened. Please help.

Hear me out, Love. You can't love two people at the same time. Ever heard of the quote "One life, one love"? Well, it's true. You can only love one man. I know this is going to sound crazy, but you should let both of em go. WHY? Well, one, your ex is an ex. He is an EXample of what you don't need in the future. NEVER go back to someone who you was with before. Things won't be the same anymore. And second, you should let this guy go because if he WAS really happy with you, then he wouldn't have done any of those stupid things. Love is powerful, Sweety. And when Love happens to you, you'll know it.
