Brok3n ~ He may THINK he's in love with this "woman" and let him go and screw up his life with her. But I STILL say that once she's gotten what she wants out of him, she'll drop him like a hot potato, and move on to someone else.
Once a cheater, ALWAYS a cheater. He won't stop cheating because he saw how easy it was to do with YOU. It's obvious that he doesn't hold women in high regard.
I just KNOW that you will find someone who will cherish you as you deserve! And your SON will have a REAL father who will love and care for him as children should have!
God bless you my friend! Take care and I hope we hear from you again. Hugs, Lee
