He lied and cheated... Would you forgive if you loved him?

Swallow your dignity and leave him. It's going to be hard for your son, but try to be the best mom for him and move on. My mom divorced my father because he cheated on her, I was five when this happened. And I am a happy 15 year old girl, who looks up to her mother for everything she sacrificed in life for me. I love my father still and I just got off the phone with him and we're having breakfast together on Satuday. It took three years for my mom to be okay enough to date again, but she is remarried and tells me all the time she is the happiest she has ever been in her entire life. God bless you! You will get through this well.
