Of course he's mad-my ex was mad as hell too because how dare I disrupt his little life....no concern of course from him as to the hell he put me and our kids through over the last few years for me to reach my limit of abuse, lies and manipulation. He will most likely blame you until he gets into recovery. If he ever does. It's his choice to blame you-but it is not your fault. You did THE right thing by getting yourself and your kids away from him!!
P.s. I chuckle to myself a little bit when I hear my ex complain about how much he misses his kids-he never did anything with them while we were together! Nothing that would cut into his drinking time each and every night! My ex misses his kids yet he has scared his daughter to the point of her shaking and not wanting to ever see him again. Right on buddy, dad of the year. Johnno-you made the absolute right decision. He's just kicking and screaming and revealing his TRUE personality to you. Move on with your life.
