Hi Reddit! I really need the unbiased opinion of internet strangers and accept any and all judgement.

For context my bf (36m) and my son and I (36f) live together and for the moment I am the main breadwinner. BF pays his portion of the rent and then I pay for everything else (food, utilities, my portion of the rent, fuel, basically everything else) and I have to budget like crazy to cover everything - I don't have a great salary either, but better than his. He's working on bettering his situation and I support us with an open heart. No resentment and no expectations on repayment. He has two kids from a previous relationship that visit us semi-regularly when he's off work. So on to the issue...

Last week he kind of sprung it on me that his kids were coming to stay the night. I asked him nicely to let me know a bit sooner next time so that I could work my money situation. I rework some things to feed all of us and everything is good (I made a butt-load of pancakes :) ). Yesterday he tells me they are coming again (I think the his ex is asking), and I ask if its after I get paid. He says no its not. I say as gently as I can that its the end of the month and I can't really afford two extra mouths right now, I'm having to borrow to make ends meet for the week as it is. He blows up. Says he doesn't see his kids and its not my responsibility and he'll sell his car for money if he has to.

I love him and I love his kids, but the reality of the situation is that I can literally not feed them too right now. I knows its just two kids and a few extra meals, but its the reality of our situation and one of the kids is a preteen that eats more than I do some days and thats ok. Please bear in mind that BF has no money at all for extra anything.

AITA for saying I'm not able to accommodate his kids right now?
