It's alarming that a woman born into Islam knows less about her Islamic rights as a wife and mother in a nikka than those of us with limited knowledge of Islam :(

They will understand all the religious and cultural sensitivities at play here. I've never used them, but I would assume they'll also help you to enforce what rights you do have legally and navigate the religious process. I hope there's someone on here who does have experience of support services for Muslim women who can give advice from their own experiences.
Women on MN are going advise you to let him leave, claim CMS, be independent and build a good, shame-free life for yourself and your children. Naturally, I think this what you should do, but I do understand that you're dealing with a lot of cultural expectations, which can be really difficult.
The facts are that you don't have rights to delay the divorce your husband wants. What you can do is ensure you claim CMS which will protect your children and ease the financial burden on you.
I will also tell you that the shame is his alone, not yours. No decent person would treat another the way he does you, especially a spouse. You and your children deserve better.
Hold your head high because you have done nothing wrong.
Do not let your life be dictated by the whims and selfishness of another person. You can live a good Muslim life while being divorced.
