By "family", I assume you mean your husband's adult children?
If so, perhaps it's time for him to tell them very firmly to grow up and stop behaving like mardy brats. He could also tell them that there will be no further financial help forthcoming until they learn to be civil to his new wife. They don't have to actually like you, just to be basically good mannered.
TBH, I find myself agreeing with Ellan - I would cerrtainly have thought long and hard before marrying into such a family. Sadly, love does not always conquer all.
When a political leader lies on their CV - can you trust them?
