I want a divorce

My husband and I have 2 kids and have been together for about 6 1/2 years. I’m not going to get into specifics as to why I want a divorce because I don’t want this post to be about that. My question is….how should I go about it? We live in a community property state. I’d like to be more financially stable (even though I’ve always been the breadwinner) before I file. I will be left to pay all the bills which I cannot afford by myself. I also thought about staying longer and buying a house because I so desperately want a house for our kids. Then when we divorce I have it in my head that we’ll have to sell the house so I wouldn’t divorce him until it’s a good time to sell the house. At that point I’ll be done with school and my business would be more established. I know it sounds crazy and maybe it is. We have a bad relationship but we don’t fight and it’s not physically abusive so our kids don’t actually know there’s a problem although I’d like to get out of it before they do start seeing the problem. Any advice from divorced women? Did you wait to save up money? Did you plan it all out or just pull the trigger? Anything you wish you would’ve known BEFORE filing? Any advice would be greatly appreciated.

Edit: He’s not open to counseling. I’m not trying to save my marriage anymore. We will eventually get a divorce.
