So, you go away on holiday for two weeks.
You come home to your clean clothes folded neatly - not something that DH has ever done before or since.
You find an unfamilar log in/e-mail on your FB account.
You confront him, his stutters and stumbles with his 'not sures' 'need to check if I created the account' to buy himself thinking time.
Then he steers the coversation towards you wanting to spilt the marriage up?
He talks about custody?
I'm so sorry but I think that there is another person involved here. Whether he has searched for them or they've been to the house, I'm not sure but he is lying.
If you cause a fuss, it's a green light for him to say that you are being unreasonable, you want to end it.
When in actual fact, it would ease his guilt and make his exit less of an issue, by blaming you, if that's what he wants IYSWIM.
He's lying, you caught him out and now his is projecting his guilt for the lies or whatever he got up to, onto you, making it all your fault.
'If you hadn't gone away, this wouldn't have happened' may well be the next line out of his mouth.
I'm so sorry you are going through this. You need to talk to him more, find out what did or didn't happen in your home.
If he has cheated or covered something up, you deserve to know why. If there is nothing going on, why let you believe that there is by lying?
It's rare though, that a guilty spouse will respect the other person enough to tell them the whole truth at the first confrontation.
Be strong and keep posting. There is some fantastic support on here.
I hope you find answers to what has been going on. x
