Well, all I can do is send you wishes of love and peace. That's definitely wrong he is texting the ex. Why are you moving? What about your kids? Have you talked to him about the money? I can feel your frustration. Mine has made purchases in the thousands of dollars range without my knowledge, all while I cut coupons and save where I can just to realize he blows our money. Have you tried counseling? I know that seems the catch all answer, but if you can find a good one, it's worth it.

Get rid of him. Hes disrespectful to you ,and apparently a stable future for you and your children are not important to him. DONT MOVE, THATS A TACTIC TO CONTROL YOU. You will not have support from your family the way you need it when your gone. Dont trust him. If he has texted the girlfriend, I'm sure it was more than just texting. Hell do it again.
