Hi Heather...
Everybody's right.... because you have always taken him back before.
I did the same thing... over and over and over.
My AH called me from the house of the woman he cheated with too... He even asked me to COME PICK HIM UP from her house once.
Thankfully, I can say that I said HELL NO to that one....
But I wanted to say I think you're doing great. You blocked him. You're not calling him back. I know it's hard.
And no, I'm sure it's not going to stop any time soon, especially with the kids involved... and like was mentioned above, it's probably time to get something established legally as far as custody.
((((hugs)))) to you!!!
