I don't care much for the things "that might happen." To be fair, tomorrow you "might" sprout a third arm.
I think it's fantastic that you've found someone to spend the rest of your life with in Ratbastid and if you see the same with these folks, what the hell is stopping you?
If the idea has been floated and everybody's on board, well, then there really isn't anything left to discuss. If things don't work out, (and it'll happen sooner rather than later) then move out. What's the hassle?
Yes, you might have hard feelings in the end, but if you're afraid of what
could happen then maybe none of us should ever leave the house.
I guess what I'm trying to say is, being afraid of what might happen is no excuse for not jumping right in. I think if you're going to run into this, then run as fast as you possibly can. You might hit the wall, but then again you might not.
