What to do

Me and my fiancé have been together for a year and a half now. We've been through a lot and I've stood by his side for everything but I feel like he's using me. I can lend him money whenever he needs but the second I ask he tells me no or never pays me back if I lend him some out of my cut for bills. The entire time we've been together he hasn't stuck with a job and is currently unemployed right now to and not trying to hard to find a job either. I don't know what to do I love him but I don't want to deal with his shit anymore at the same time. Help!
