OMG, Aerrica
. His name isn't ANGUS, is it???? I have a brother who's just about the same way (only he DOES shower daily). It's so hard to turn your back on someone esp a family member when they're down.
I know this sounds so simple, but your husband should only allow him to move in with you under certain stipulations....like, he has to shower at least every other day (or whatever you all think is tolerable) and he HAS to help out around the house, and he HAS to ....fill in the blank. It's up to you to set the rules and guidelines and stick to them. If he can't follow them in YOUR home, then he needs to leave. And that's how it should be. I feel so bad for you b/c you JUST got into your house! Anyway, if he wants help. he needs to respect you and your home and the serenity of running it YOUR way. If he can't, then I'd tell him ahead of time, this is the way it is; we're happy to help you out for (however long), but if you can't respect our wishes then maybe you can find someone else to help you out.
It's hard no matter who it is or what the circumstances are, but it's YOUR home and you deserve to feel comfortable in it and not be taken advantage of in it. Stay strong! And yes, make sure he's out looking for work! Good luck honey~
