Want to leave my marriage of 13 years, we have 4 kids together ages 12,10,10 & 8

There’s nothing left here in our marriage except the kids. We DO NOT ever argue. There’s just no affection, fun, etc

Yes I’ve talked to him about my frustrations he said deal with it

But idk how I don’t have money to get my own place or anything. I’m 31 and don’t drive either.....

What do I do or go about this?m

EDIT HE DOES NOT WORK HE HAS A KIDNEY TRANSPLANT

I work ALL the time

I got married REALLY young pretty much right after high school

I’m 31

He’s 47

There’s nothing here anymore

Counseling’s our of the picture

I’ve never dated anyone but him

He’s doesn’t cheat 🤦🏽‍♀️
