Another question SD, I had to ask it, but it needs to be asked.
Is there any risk that your H may react violently?
In many cases here after exposure the LBS will post here saying things like "I have NEVER seen him that ANGRY... He was a completely different person."
I don't recall any actual violence coming from exposure but I would like to confirm with others.
Particularly given He will be back in three months and you share a home its very important that you think this through...
You COULD have a friend stay with you for the three months and have them stay there upon his return as well.
