ValentineBombshell... I too have read all of your thread tonight and I'm in awe of your composure. I think you're getting to a tough(er) bit now that all you can do, ie. chuck him out, instruct solicitors, sort out arrangements for access to the DCs, has been done (and very competently, in my opinion) but it's leaving you possibly with a feeling of 'What do I do now?'. Your H is still on the scene, like a frustrated tomcat, trying to 'spray' you with his ridiculous questions/notions and general twattery involving access so that you don't get him out of your head. In a way, he's like a child, any attention is good whether it's positive or not.
As far as your laptop goes, I wouldn't trust him an inch. If you feel so inclined, get a new cheap pen drive and just copy over his essential stuff. He's had ample time to prepare for leaving - you were the one who had to react to his selfishness and had no time to assimilate it all. Give him his job stuff, let him whistle for his music, not your concern and not your priority.
You've had some great support on this thread about disengaging and you're doing a fabulous job of it... it's just that he's like a stuck record, he keeps trying again and again and because you're a decent person, you answer what you think is reasonable. Because he's not decent, he thinks nothing of bothering you and jabbing at you whenever he can.
I don't know what would be a short, sharp message to him, but perhaps you could ask your solicitor - and ask her to send him a letter to desist talking about anything that is not strictly necessary and to address all queries through the legal channels. I think it would be money well spent if it protects you right now, VB, it's just too much. Your H is so very selfish and either he doesn't care how it affects your children or he's just too stupid and wrapped up himself to think beyond his own ignorant wants. I'd love to slap him. How proud his parents must be of him.
You don't need him or want him, it's bothering him. That's a good thing, but he's got to leave you alone.
Focus only on you and your DCs and nevermind what HE wants. Thinking of you and rooting for you to be well on the way to building your new fabulous life with no more thought of your H who will be standing on the sidelines lamenting what he used to have and threw away and he can regret that on his own time for as long as he likes.
