What do I do? Leave him orrr?

Me and my husband just had our third maybe in May. After realizing that everything is just so expensive with food, formula, diapers, life in general, etc. I had a conversation with him that his pay just isn’t cutting it. I make $2 more than him and carry the insurance. His paychecks are not much. He has a job opportunity with a $2 raise & insurance is cheaper if jus t himself gets on it so my insurance would be cheaper too for myself and the kids. The insurance at his current job is EXPENSIVE for just him. While talking last night and the night before, I couldn’t stop crying talking about how stressed I am. We are living paycheck to paycheck right now. There’s more that we need to pay for coming up too. He told me he doesn’t want to leave his current job because he really likes the company. He’s also made good buddies there. He told me that he would do anything and now that there is an offer out there he literally won’t leave his job. I’m tired of being the one paying the bills & having to worry about how we’re going to make it to the next week. I do the dinner planning, cleaning, cooking, bathing kids, etc. he will do that stuff IF I ask. I’m done. He will not take me serious jsut says “not everything has to be tears” or “everything will be fine” he would make $10k more a year with this new job plus be able to get his own insurance and give me even more money on my paycheck. What do I do? Idk what else to do. I told him maybe I could find a different job to make more money & he literally told me I should???? Like what
