20 years married, 4 boys, younger teens to primary school age.
Long story short: H has cheated for years, I found out a couple of years ago, lots of relationship counselling, try again, now OW 'means more' and we are separated. While I am gutted that our marriage has come to this, it IS the only way. I can never trust him again and, broken heart aside, have lost all respect for him.
Things are civil, at times even amicable, it has only been 3 months since he moved out.
So far, so good.
We are looking at finances, I am hoping to be able to keep the house in order to disrupt the kids' lives a little as possible.
However - he is still in that place where he is quite enjoying the bachelor lifestyle, see OW, going out etc etc while seeing the boys as and when it suits him. Now, while I really do not want to EVER use the children as bargaining chips and I am very keen that they maintain a relationship with him (the are smart kids, they know what he has done/is doing), I want him to share the parenting load rather than me doing everything and him being the archetypical Disney Dad.
Any tips?
His job involves a complicated rota including overnights/weekends/antisocial hours, so simply saying 'every other weekend' just does not work. He is currently in a (rented) flat which is not big enough to accommodate all of them over night and he does not see a problem with that 
I am still reeling with disbelief that I clearly did not know the man I have known for 24 years AT ALL
