You have the right to choose your own attorney. If your lawyer has been failing to file things for you and ignoring you, then you certainly have a good reason to want a new one. If you find a new lawyer and hire them, they can file a form called a 'notice of substitution of counsel,' which allows the old attorney to withdraw and makes the new one responsible for the case, all at once.
Otherwise, an attorney who has appeared in a case (that is, who has filed any papers with the court) can't just 'quit' in the middle of a case - they need to get the court's permission to withdraw. This is true even if you want to fire them - but the court will certainly grant permission for them to withdraw, if that is the reason.
When a lawyer withdraws from representing you, then you have the right to get your entire file from them. You also have a right to a refund of any unearned retainer they hold for you (though they can still bill you for work they've done already).
If your attorney does get an order to withdraw before you find a new one, your husband and his lawyer will not "eat you alive" in the meantime. You can just tell them that you're looking for a new lawyer and have some patience. Courts in family law cases focus heavily on getting a fair outcome rather than rewarding the most cunning legal tricks, and place a high premium on civility. Any rudeness or unprofessionalism that your husband or especially his lawyer show to you is a bit of a gift, to you - it makes them look that much worse. That said, it is important to be represented, so you should find another lawyer if your current one isn't doing well for you.
