not much you can do, if your mother in law could help, and you might not like or want to risk what you will need to do, there is a something called 'Right of Access to A Child rule', which is complex and it would not be easy, and may not be possible in your case, and this rule could be scrapped soon.

seek legal advice thou, but you may find many solicitors/lawyers don't know about this rule..
but maybe it would be better if you and your hubby, maybe his mother could persuade him to help you and his daughter stay in the uk, maybe using this rule.
good luck
