What y’all do if y’all living with ur bf parents house n ur mother in law remarried who is young who is 27 and she 40 but he doesn’t work only (uber). And the brothers smoke weed but they don’t work and the step dad asking your bf to help him to pay lights bills twice? They always ask him a lot favors especially the Brothers that they don’t clean that they don’t work they just out there smoking. He can’t even say no to them I mean I always tell him they just using you why can’t u see that especially we’re expecting a kid on the way to December?! I need some advice or what y’all do?
