Oh, dear, so he has moved three hours away?
And you feel he has already moved on, so to speak....

Well, I know, truly understand, that you are hurting.
It does sound, though, from what you have shared, that this man is not being good to you or for you...and your children.

I am glad to hear that you are employed, and have your own residence. Did you invest money with this man in his new business? Not sure what this means legally in regard to your situation, but I hope you didn't give him lots of money.

The only advice I can give right now..is to take care of yourself and your children first. It sounds like you have already been hurt by this man previously, during your pregnancy, so you know the score regarding emotional pain and recovery. It takes precious time, but in the end you will ultimately become stronger and wiser for it.

Others here will have even wiser and more insightful feedback for you...I'm certain of this.
Hang in there and be well.
Love
Patty
