Harman, have just read through your post and most of the replies. I do sympathise with you, it seems like so many ex partners/husbands use the children to hold on to that last bit of control over us and it makes me sick. I am having similar problems with my ex h. I tried emailing him and that was on 11th sept., so far the ignorant git hasn't had the courtesy to reply.
My particular problem is with the drop off/collection. I am now refusing to drive to meet ex h as I feel he is being unreasonable, he travels about 15 miles and me about 30 on the Sunday and on the Friday I deliver them to his place of work, yet when I tried to alter the venue on a sunday to a halfway point he threw his toys out the pram! He is next due to have the children next weekend however because of his bloody unreasonable behaviour I have now decided to take back the control. I am going to say that he can see the children every other weekend as he has been but he needs to collect them and drop them home. He earns about 80k and I am not currently working.
Can he force me to drive anywhere if he takes this to court or am I within my rights to insist he comes to the house? We have no laid down collection/drop off, the only thing that was stipulated in the divorce settlement was he has the children every other weekend.
Like your ex p he often makes excuses why he shouldn't have them any extra nights. If he ever wants to swap a weekend I go out of my way to be flexible, if I ask him to have them for example on Sunday night as a favour once in a while he always refuses. Its like he thinks he does me a favour by, like others have said, "babysitting" every other weekend, instead of viewing it as quality time with his children.
I am taking the control back and he is going to be in for a shock. Previously I think he knows that I desperately need that break every other weekend and used it as a way of continuing to control me. Unlucky for him the worm has turned!!
Good luck with your situation.
