Unexpected walk-away-husband

[jpLove]

I could really use advice today. H texted me earlier and told me that he thinks I need to consider moving in with my parents. That means moving me & soon to be 3 children into my parents' 1300 sq ft house where my 68 year old mom is in ill health. The three kids and I would have a bedroom...and all of my furniture and belongings would have to go into storage. All because he can't financially support the decision he's made. I don't have a job because we both wanted our kids to have a stay home mom, and I'm 20 weeks pregnant. Getting a job isn't really a viable option at the moment, but moving in with my parents is even less viable. I've been following strict rules on communication with him but I'm stumped now. Part of me thinks I need to arrange a meeting with him where I lay it down. Why our problems aren't irreconcilable (no one was abusive, we get along very well, and there was/is no affair.) the ramifications both emotionally and financially of divorce for both of us and the kids, why us abandoning our house is not an option, and proposing that he needs to go to a retrouville weekend with me. I've never stood up to him so I have no idea how it will go. (Not because I was afraid of him, because I was needy and submissive.). Any and all ideas/advice is very needed and very welcome! Thank you!
