Background : I have 3 children who are not my partners, they live with me half of the month, the other half with their dad. My partner moved in with us 2 years ago. He has no children. He pays me £400 per month, as before he lived with me he lived with his sibling and that was what he paid them, and we agreed it wouldn't be fair for him to pay 50% of household bills as my outgoings are more due to my children. My bills have raised significantly since he has been here, mostly food, as he will not eat a single meal that doesn't have meat, whereas we used to eat mainly veggie.
I work full time. A few months ago, he lost his job. Since then, he has been actively job searching, had plenty of interviews and 3 job offers. He declined the first one as he didn't like the early start time, he declined the second because it was too far away, and the third because he wanted a higher wage (it was above minimum wage, and only paid 3k a year less than me as a healthcare professional). I think he has high expectations / demands for which jobs he is willing to accept as he has minimal qualifications and works in a manual job think along the lines of a labourer on a site.
I don't really know what my AIBU is, but I am fed up of coming home after a 13 hour shift, to find him gaming and the house is a mess - dishes not done, washing left on the line to be rained on, the other day he was eating his tea when I got back but when I asked if the kids had eaten he said he thought he would have fed themselves, so he hadn't actually fed them and the youngest is only 9. He also sits up until 3am talking into his headset, which really disturbs my sleep and I need to be up at 5am for work. He doesn't get out of bed till after lunchtime, when I work nightshift I have to come home, take the dog out, feed the dog and do all the washing / food prep before I go to bed as he just wouldn't. Financially I am struggling because now not only do I not have the £400 from him each month, I also have to pay his bills for him (car, hobby,alcohol, phone).
AIBU to think he should accept any job he is offered and then look for a better one when he is employed?
