Hi I have just read your thread and had to post because sooo much of what is being written has bought back memories of my XH
I am exactly five years down the line from him leaving hooking up with an OW on his way out the door. We had been together 17 years with two DC
The first couple of months were awful mostly because I was terrified of what the future held as I was a SAHM and knew I would have to get out there and build a life and also I had no idea how my DC would cope. However I was so determined that having given him so many years where he treated me badly that I didn't want to waste any more time and emotion on him.
To that end I read every divorce book going, undertook psychotherapy , leant on every friend and took every bit of support going. i should add my recovery was assisted by the certain knowledge from day one that our split was for the best and needed to happen. Even with all that it took months before the sheer physical side of heartbreak went away never mind the mental side.
I completely agree with those that have said the only real healer is time and unfortunately there are no short cuts through this. I think it's better to just go with it and allow yourself to grieve without any pressure to be ok with it. When I discovered MN it was such a relief to mix with people who understood just how all encompassing how truly devastating the end of a marriage , even a bad one, can be.
One thing you will be spared OP which I found hardest of all is your DC going to them every other weekend and becoming involved in a whole life you know nothing about. I took the route of maintaining XHs image and dignity in my DCs eyes and that was horrendous at times but for the best.
This time of year is full of memories , bad ones, as its when we were going through our split and five years on some linger.
Its a bit early to be giving this advice but please make sure you fight for exactly what you are legally entitled to no more but no less. Remember he can say whatever he likes about what he will or won't do financially but he may as well tell it to the mountain because the law will protect you. I saw a solicitor early on just to get the lay of the land and so when my XH started blustering about this and that I just thought " whatever" . Be warned that's when you really get a shock how you rank in their lives and it's incredibly hurtful but that's the time you need to stand tough. Unfortunately it's very cruel timing that when you are so vulnerable you have to be strong.
Anyway I'm rambling a bit now but know you will be happy again and that the pain and rage does subside. If your like me you come out the other end a better and happier person. I had no choice but to stand on my own two feet and it's been the making of me even if in other material respects my life is harder. I've clawed my way back into work , can unblock a toilet and loads of other stuff !
