Can I Resolve The Issues Without Him?

I wonder if I will ever be able to resolve the issues between us. I just don't know how, if he only gave me lies as answers to my questions. All I wanted to know was "why" but he said he didn't know. I wanted to know how could he keep telling me he loved me while he was out with "her". That's not love. I really want to be able to resolve all those issues, but I find that it's so hard to move on, especially when you don't have the answers to the questions. It's hard going through a divorce, knowing that you tried your very hardest to keep things together but he just didn't care enough to work with you. How do you resolve this in your head without being able to work through it all?
