Are you really serious?
You would stay with a man who has told you over and over that he does not love you and will continue to pursue other women?
It's time for a reality check, you are a mother and an independent woman so it's time to stand up for yourself and your feelings.
If you honestly believe he will make it big then good for him let him pursue his dreams just keep in mind you have a child by him so he will have to support his child and the more he makes the more your child will get. But don't hold on to a relationship when you know he isn't happy.
Money can't buy love.
