Agree with Train on the coffee and the MA, for precisely the reasons she stated.
As for the marital bed, that's a sensitive one. The one "given" around here is that YOU (the betrayed spouse) should never leave the marital bed and almost never leave the marital home. If the wayward spouse is uncomfortable there, then SHE should leave.
I personally never asked my wife to leave our bedroom, and nor did I object when she decided to do it on her own. Many wayward spouses will do it on their own, either out of guilt/shame, or a belief that they're actually "cheating" on their affair partner while sleeping there (yeah, I know), or -- much more pragmatically -- they just want to be able to do a late next phone or heavy texting session with their affair partner, unencumbered.
I would say to do whatever feels authentic to you.
