would u wait for someone doing up to a year in jail if u been together for 3 years already?

No. You deserve someone better. Make a clean break, enjoy being single, and after you have had time to recover from this situation, find someone who is honest and treats you well.

No, after all having a record is going to make his life difficult for years to come. He'll never really get a job without them knowing it, and that's going to limit his earnings for all time. And, depending on what he's in for, it may be that he'd end up being sent back doing the same thing again. No matter what he says now.

Especially if its for a violent crime, that means he's got a temper he can't control.

Nope. If they did something to actually get put in jail, then they are a worthless criminal scumbag not worthy of my time or energy.
