I am in the process of suing a cheating fiance right now to get back a ring. In Michigan an engagement ring is a conditional gift no marriage you get the ring back period. As to the debts if they were joint, or hers, they are hers (or at most partially yours) if they were in your name they are presumably yours. That is the problem with co-habitation if you do not have a prior agreement on who pays what.. finances get confused and you do not have the benefit of marriage/divorce laws to sort out the respective responsibilities.
