When I ask him to sort it out and make and effort his reply is “I don’t have to make an effort, I’ve already got you. I don’t have to impress you anymore”.
So he really feels so little for you that he believes this? And he believes this because you've been unable/unwilling to follow through?
What do you actually want to do about this - barring any more ultimatum which he will not believe?
And when we actually do DTD he doesn’t smell clean at all, even though he’s showered before hand. It feels like his hygiene is so sparse that when he does decide to wash it’s just scraping the surface.
Ugh! This is just muddying the waters - I'm not sure I'd go there even if I was grateful he'd had a wash.
No he doesn’t work hard. He’s only working at the place where he is now because I applied for it for him. He lost his previous job because he kept calling in sick.
You seem to be the only one working on your "partnership" - why do you put up with this? And what lessons are your DC learning from this?
Why are you with someone who doesn't care about you, or your DC, or his job, etc to do anything positive for your relationship?
Sorry OP but you surely deserve more than this?!
Great you are applying for other jobs but I also suggest you speak with Citizens Advice to see what benefits you might be entitled to if (when) you give him his marching orders or go online to https://www.entitledto.co.ukk_. You may find that you are in a better place financially once you have split up and give you some breathing space whilst you get settled, look for a new job, childcare etc.
Also agree with Anyfucker.
