I was in a relationship for 18 years (married 7 of those). Two children now 9 and 4.
21 months ago ex told me he was leaving but to be honest I'd come to that conclusion - he had been too horrible to me for too long and I could see how it was affecting the eldest - looking back I had seen this years before :( He said he would leave the house in 6 months time and in the meanwhile I would need to give him half the equity of the house and he would be having the children half of the time. I did have some savings and so managed to buy him out and I grieved over the children but thought as their dad it was his right to spend time with them. After 6 horrible months (and 2 holidays together) he finally left (I'd been sleeping ona matress on the floor of the spare room all this time even when the house was in my name. He also tried to persuade me not to tell anyone and I can't believe I didn't even tell my parents for a couple of months because of this. When I told him I was going to see them to tell them he tried to persuade me now to by saying how angry he'd be if I came back all argumentative.
For years he'd threaten to leave because of thing like me not shutting doors, I always felt that if I tried harder it would all be OK and so I'd make his meals, cups of tea, let him lie in (I don't think he ever got up with the kids, even when I was ill). I tried not to get annoyed when he'd go out to football 2 or 3 or 4 nights a week straight from work and come back in after midnight. Or the not so odd night he'd come in at 3 or 4 ...
A couple of weeks (or maybe less?) after he'd left the girls were continually talking about a woman who was spending a lot of time with them. I also had strongly suspected a few months before that he was seeing someone
sorry - to get to the point. Last year he was working 5 days, I work 3 and have DD2 the other 2 (always been one of the things he'd get at me about). I would do all the pickups and teas, even on 'his' nights with the kids and we had a complicated arrangement of nights. He didn't work for the first 3 months leaving (said he couldn't concentrate being at work when he had to sort out his house) and then took voluntary redundancy 6 months after that. All of that time he never offered to do pickups although I did ask him to sometimes if I had an event on at work - he calls this doing a favour for me 
This year he's not working and sufddenly decided he wants DD2 one day a week (she's still not at school, and is at preschool 3 days) and to do the pick ups on his days. He's also being really difficult about weekends - he's happy to book 5 days away and miss a weekend but then want them most of the weekend before and after, but when I'm missing a weekend with them he won't agree that for me. He sends me insulting critical e-mails in response to my polite ones. I've tried to suggest we alternate weekends partly as this is what DD1 would like, and partly so we don't have to negotiate each one separately (and we don't have to communicate as much). He's said no to this. At the moment I have them every Friday and one of them every Saturday, so this is another reason to alternate.
This doesn't seem like much but every time he asks for something I tend to agree, when I do he makes it so difficult. If I want to go out Friday or Saturday I've had to negotiate with him and if he doesn't like something I say he'll just say'n' at the last moment. On several occasions I've had the kids at the last minute on his request. He's also always late which has caused problems for me and on occasions distress for the kids. Generally, though, he is a good Dad.
In addition I have evidence that he's trying to sabotage a holiday that I was trying to organise for the kids next summer. He shouts at me in front of them is has drawn DD1 into arguments.
We're going to mediation in the next few weeks to sort out things with the kisd. I'm half looking forward to it (I suggested it last year, but he said it was pointless as I was no good at negotiating) and half dreading having to be with him bullying me - can't believe in many ways I'm so strong.
Sorry - that's long enough
I just want to know when this all starts getting easier - I'm fine by myslef, cope practicall. Financially is hard but I'm getting there. Don't miss him although I miss the kids when they're with him. It's just all the insults and argueing. I just want the negotiations to be more straightforward. It's always going to be emotional trying to negotiate time with the kids, but it feels like I have to fight to make it fair. He jsut wants them on his terms (and then to be able to book a week away here and there when he fancies)
I don't want to dread the e-mails, to wonder what's happening next weekend. I don't want to worry about what he's saying to the kids.
I want to be able to get on with my life and this is taking up too much time and energy.
Any advice would be gratefully received
