What new skills have you all learned? When do you mostly feel judged?
Organisational/time management skills. I have more confidence in myself and my abilities. I also know how to deal with a crisis without having to rely on someone else.
I don't feel so judged in real life, mainly when people make shitty comments online about single parents.
I'm not expecting h to leave the house for a couple of months. How best can I use that time?
Preparing the kids emotionally for when he leaves? I think that is something he can help with (possibly?) so that it's not all on you when he does go? Could he move out gradually? is that something that is possible? So maybe him staying out of the house for say two nights a week for a while, then four nights a week for a while and so on. Might help to ease the children into it, especially with them being young and perhaps not able to fully understand what's going on - be less of a shock then daddys here one minute and then he's gone.
Are there any household jobs you need doing that you can't do? Ask him if he can do them while he's there so you don't need to worry about a handy man later. Is there any jobs he usually deals with that you're unsure about? get him to show you how he deals with it.
Does he have the number of the plumber/electrician etc that you usually use? get it from him now so you won't be stuck in the future if he's got his phone off or whatever.
Any heavy lifting of things that you no longer want/need that needs taking to the tip that you won't manage by yourself? Get him roped in before he goes. One less thing to worry about when he's gone. Ex left me with so much stuff in the shed, as a non driver and most the stuff being heavy I've found it a nightmare to shift on my own.
Of course in an ideal world these will be things he can/will help with after he's gone. But the world is less than ideal and he may not always be available when you need a hand. The above are just things that come to mind that I would have liked ex to help me with before going that he promised to do when he'd moved out and didn't.
