Every relationship is different. I know how hard it is right now for you, trust me I went through he@@ and am pretty much still there even though my H and OW are no longer together and he lives on my couch........
Honestly my best advice to you is try not to think about the affair 24/7. I personally know that is easier said than done. Make yourself as busy as possible and keep your mind busy at all times.
