Have posted previously and received some great support, so here I am again.
Brief recap: married for 12 years with 3 DC. Emotionally and physically abusive marriage in which I fell out of love and decided I wanted to end it last summer. Constant walking on eggshells, feelings of not being good enough, resentment etc. He left the marital home and I stayed with the DCs.
I have no surviving family and because of his living circumstances where a friend has recently moved in, it means I have primary care of the children, and for at least 6 weeks now, this has been without a break. I have struggled, a lot. I have been put on anti ds by my GP due to lack of confidence as a result of being put down so many years.
For the sake of the children, we are trying to remain civil. He is due to open a new business this week and has been tied up there as a result. Its a good 15-20 minute drive in the opposite direction from school to home and over half term last week, I made the effort and took the kids to see him there most days whilst I knew he didn't have much flexibility. If I hadn't have done this, he wouldn't have had the time and so at least he can't throw it back in my face about me not making an effort on my part- or so I thought.
After school tonight, they said they wanted to see him. I called to check if he was available and he said to bring them across. We must have stayed around 30 minutes, and in that time, all they got was a hello and a kiss on the cheek. When I realised he was too busy to come and sit with them, I told them that it would be best if we left as I also didn't want to get stuck in rush hour traffic. He then made some smart comment directly to the children about me being bored, and that when I brought them tomorrow he would take them home so they could stay longer. Stay longer and
do what? Sit on a table and watch their father do anything and everything but interact with them when his business partner was happily sitting with his own DW and DD when we arrived?
When I told him that I had brought the children to see him, which on the phone he had no problem with, he replied that I wasn't doing him a favour, I was doing the children a favour  I actually thought he would appreciate me making the effort to bring the kids to him as much as I have, because I don't want them turning around in a few years time telling me that I was the reason they never saw him, when in fact, if it was left to him, they probably wouldn't see half of what they are doing now.
This coming from a guy who was adamant on joint custody, yet hasn't looked after his kids once in the past six weeks at least.
I am tired, burning out, and trying to juggle life with three DC, one of whom has a disability. All the while trying to keep their relationship with their father healthy, yet I get the feeling I just have mug written across my face
