Good Morning!
You are the bad guy in his family. He is the bad guy in your family. Once you have your own household you will be Your Own Family.
Don’t promise your family anything. If they bring him up say you don’t want to talk about it. Once you have that stable job, find affordable day care and move out into your new place. Your husband will have to step up and help with that.
Right now the baby is the first priority and you can’t do anything without childcare. Even if it’s from your family. Or you while he works and you budget like crazy!
But make it clear that you are not moving back in with family. Even if you live in a one room apartment while he works and you’re a stay at home mom, that is the best option. I would do that myself until he’s school age and then find a part time job.
Though I run this site, it is not mine. It's ours. It's not about me. It's about us. Your stories and your wisdom are just as meaningful as mine.
