I Keep Leaving because Nothing Changes, How Can I Fix Things?

I've been dating this guy for 6 months now~ we live off grid & the living situation is kinda rough. He's been saying for weeks that he's gonna hook up the washer/dryer & finish the shower. That its really easy.. but then he just doesn't. I've broken down to him cuz I dont shower for days & feel gross. Sometimes I get mad & ask him why he tells me something & doesn't follow through. I dont try to make him feel bad but me expressing my feelings upsets him. I've been going to my moms, or my friends recenly so I can shower & take care of myself. Tonight when I left he said its getting easier watching me leave. Im really bummed & just would like some advice... it seems like he's just lost all motivation.
