We've been married for almost 2 years but been together over 4 years. I supported him while he was in prison for at least a couple of years. I have receipts and he even signed a couples agreement that if we split within 3 years of his release he'd have to pay me $5000 a year for every year I supported him, the only thing it's not notarized. Do I have any chance of recouping what I put into him??
