Am I being an asshole

I’ve been with my SO since 2015.

Recently moved into a place and yeah we’ve been struggling a little. He’s awful with money so I tell him you need to put *at the very least x amount* and not touch it. well weve been together this long I’m not new to this, his way of thinking is very “we’ll figure it out” but “we” don’t figure anything out he spends all his money on a spending spree and then expects me to figure something out. Begs me to ask family members when they’re struggling themselves and if I don’t it’s ‘I don’t get why you won’t help me’ back when I had a job he would spend all his money cause he knew I love to save money and I’d end up spending over 100 on him everytime. I don’t mind helping out at all is give him the world if I could which is why I don’t get it. it’s just the him spending all his and expecting me everytime to figure something out. It’s honestly exhausting to someone with severe anxiety. We, but mainly he decided it would be best for me to stay home with the kids, cheaper. It kills me not having a job or money. I go without on stuff that should be considered necessities like body wash, shampoo, razors so my kids don’t have to go without. He’s more of a he can’t go without anything type of person. It’s almost like He’s gonna get what he needs/wants and to hell with us. Even if it’s a 10$ pack of sodas or 70$ spent on vapes. While we don’t even have bare minimum stuff. The first two weeks of being here we were hurting real bad like not even spare change broke cause he can’t handle money if the choice is him go without or us it’s always us. So I come on here asking for advice/insight from other ppl cause he says I act crazy cause I’m upset about it all.
