*Should I fight custody?*already signed sep.agr

[cat03]

I'm sorry to hear that Donna, but do try to talk to him, I learned tons about what to do/not to do about our children's pain in the the book "healing the hurt restoring the hope' give that a try, he needs to let it out, if not, always leave the door open to give him a chance to let it out, it gets extra hard when they are teens)))))

thanks peace, the gf's grip goes beyond the imaginable. For some strange reason she makes him reduce the amount of time kids speak to me, tries to get rid of any flexibility stbx and I agreed upon at the beginning of the S, it's horrible.
ANYtime we have to agreed on something he turns to her (yes, I hear him) and ask him "is this ok?" aRGH!!!!!!!!!!! even if it is to the best advantage of the kids he goes with what she says.

I finally had it and let it know that I know she is texting as him, after my reply she didnt' refute nor text back (she had just sent a very rude text and was mean talking about my d5) My reply was not hateful nor angry, only said pretty much that if stbx had something to say, to call me, that I wans't havign another txt fight.

This is where I need your help. When stbx picked up d5 (it was the worst time, she sobbed and refused to go, he stood there blank faced telling her to go, no hugs nothing, he comes back from the car as she sobbed to talk about some bill. I was so mad, I tell him to just go, he snaps at me "she'll be FINE!" and takes his time, I finally snatched the bill (which was old, something we could've talked on the phone about it) and shut the door.
He makes her sit on the FRONT seat (he came on her car, which is clean and there is space in the back) Now, d5 was terribly upset and the drive to his home is of 3min, those were the only reasons I didnt' come out to make her sit in the back.

I gave him a booster seat last year, the kind that is a half one, doesn't take any space or anything. S10 tells me she never wears one (neither gf's s6 who is a tiny skinny boy who could really need it). I cannot let him endanger my d5 like that, I told him on a vm that I wouldn't let him take d5 without one, his only reply was to not threaten him. Other than that what can i do??? I will never forgive myself if something happens to her and I didnt' do enough to protect her.

The D papers aren't final yet, the sep. agreement can be amended but only if he agrees, i want to put there that she will not go with him unless I see the booster seat when he picks her up, I dont know what else to do. My d5 will be 6 in 3wks, she is a big girl, weights 65lbs and is 48" tall, but VA law says a child has to be 8 and 80lbs.
I dont think she sits in the front often, he always has her sit in the back, but the booster seat thing is killing me.
