The problem is, throwing the spouse OUT does NOT have this impact, they still have a home, they just get a vacation from it... it doens't bother them really... they KNOW they can return ANY TIME and are WELCOME... How is this constructive in busting an affair?

Don't throw them out, take their HOME away. Rip the rug right out from under them and tell them they can't have their cake and eat it too...

Show them they dont' DESERVE a home while they are cheating, and that until they start playing fair, they don't HAVE a home anymore... TIME OUT
