I know what you're going through. The same happened to me. I was married for 15 years and most of that time my husband cheatet on me. I found out later, but I always knew that something was going on. Text messages to woman, dating pages, hiding his phone ext.
Now he's dating a married woman and he manipulated me so much that I left him.
I'm free now and that is good, but I feel hurt, sad, broken..
God has a plan for all of us!
It hurts, but we are not alone! It will get better! I hope so!
