What to do with pets when you divorce?

We adopted three cats from a shelter. Two are adults that are bonded and best friends, but one is in my name and the other is in my husband’s. The third is a kitten in my name. I think my husband is unwilling to let go of the cat in his name, but he is completely bonded to the other cat and it would kill them to be separated...I personally rescued the other bonded cat so I don’t want to let him go either. Any thoughts? This is making the whole thing so much more painful.
