Hi Rjtal29:
Thankyou for the kind complements. That is very generous of you and too much, really.
He LIVES for the argument and will do anything to try to pull me in.
This must be an N trait because it's very popular!!!
So.......the trick then is ......to not let him pull you in, right? You can decide not to let him (not that anything is easy but if you start working at this now.....and keep trying....after awhile.....you will be an expert and it won't seem so difficult!!).
I'm glad you only speak by phone and not too often!! So, he's in violation of your marital agreement eh? And he has no working pc? I bet!!!

As if!! Good excuse though eh?
...he started to send me obnoxious monologues and berate me about my motherhood, etc.
I agree with those who have advised you to ignor his crazy talk. Example of how this could go now:
He says: "You are a crappy mother."
You say: "So what time are you picking the kids up tomorrow?"
He says: "And not only that but you're fat and ugly and you smell bad!"
You say: "Probably the usual eh? 7 pm. Ok then."
He says: "You're a b------- and a c------- and f--------n cow too!"
You say: "There seems to be a problem with our connection. I can't hear what you're saying. I'll have the children ready by 7pm tomorrow. Bye for now."
Hang up and imagine the total and utter confusion on his face.

He claims that it is all about me and my selfish desires.
More potential examples:
He says: "You only want _______(son) in singing so you can have your selfish need met to see him up on a stage, like some star, to make yourself look like a great mother!!"
You say: "_______(son) is such a good singer isn't he? I bet you're proud of his effort and how well he does when he's performing. I wonder if he gets that from your side of the family?"
He says: "You want _______(son) in karate because it's all about you and your need to have a big, tough, son, so you can look like you you've done this marvelous job of raising him!!"
You say: "_______(son) is learning so many skills in karate that will help him become a responsible adult. I bet you're glad he's trying so hard and putting such a good effort into learning karate. I know it's inconvenient to take him to practice sometimes but I bet you don't mind."
I my experience with these people, if I turn their insults of me into some positive statement about them......they get that ....pathetic.....confused look on their face and it seems to shut them up fairly quick. This may or may not work with your ex. Worth a try maybe???
My ex is trying to manipulate my children to not do these things and he almost succeeded!
I know where you're coming from. This is very frustrating and upsetting. It makes me angry to think about and it makes me want to go over there and hog tie him to a hydro pole and throw paper airplanes at him (complete with my opinions typed inside them)!!!

However.....this is probably the response he wants. So....don't give it to him. Instead, keep encouraging your children, reminding them of all the benefits of their activities, how proud you are of their involvement in those activities, how glad you are that they enjoy those things, how you look forward to their karate belt exams and muscial performances...etc. You're not manipulating them by encouraging them to participate in stuff they like that will benefit them. I have no qualms with you manipulating him into thinking it's all his talents they've inherited, how good it makes him look, what a great dad he is for taking them to their practices, etc. For your kids.......whatever helps make their lives easier......manipulate away!! Better you than him!!
I just can't believe that he can be such a jerk!!
It's hard to believe any parent would behave like him but he's really not a parent. He's a toddler trying to look like a parent. He hasn't got a clue how to parent or at least.....much desire.

I will defiinitely take your advice and try not to react because I think that is really the smartest thing. He LOVES it when I react, it makes him feel alive.
Exactly!! Good for you!!! Do your best!! Don't let him push your buttons.....or think what he says has any effect on you. It will take a little bit of practice but you'll get there!! Count to 5 before replying? Take a deep breath? Imagine him in a diaper? Whatever helps you to be cool and calm and adult....will likely help.
I'm so glad to hear that you are happily married now!! That is so wonderful to hear!! Thanks for sharing your hope!!
