Lumpy I spotted that one the other day; it didn't half make me cackle.
I think one of the most important things I learnt from MN is: it doesn't matter whether he's being intentionally malicious or abusing you on purpose. What matters is the effect on you.
miricles my ex is completely incapable of holding down a job. He reckons it's due to depression. I have sympathy - I struggle to work due to my MH so I know what it's like - but the difference between us is, I went to the doctor's, I got myself on ESA, I found my way to the appropriate therapy services and am engaging with them. He just sits on his arse feeling gloomy and doing nothing about it.
First time I kicked him out, DD was too young to need an explanation. Some years later he ended up on my sofa because he'd failed to pay his rent - didn't want to see him on the streets so said he could sleep there temporarily while he sorted himself a place.
I then spent about a year slowly going completely demented while he sat on the sofa doing fuck all about the fact he was technically homeless - because I didn't want DD to see me abandoning her father to live on the streets.
Finally got drunk, chatted honestly to my support people about what was going on, got psyched myself up, and told him to give me the keys back and gtfo. He went and slept on a mate's sofa and had sorted a new place within a month.
DD always gets the same explanation: I don't know why daddy does ABC, but it makes me feel like XYZ, and I can't live like that, so I don't; and daddy is a grown-up, it's up to him to look after himself.
You wouldn't be kicking him out with nothing, miricles. You'd be kicking him out with a social security system there to pick up the slack. And if the horrors of universal credit don't get him to pull his finger out and take some responsibility, well, that's his problem.
