I understand that if cheating occured during the marriage, alimony is no longer in play for the divorce. My question is: when does it come back into play. If we are trying to work on reconciliation and we are sharing a bed every night. How long do we have to use cheating as the reason for divorce, and alimony is forfeited?

It depends on the circumstances in each case. If the wronged party actually forgives the other party for adultery, “condonation” can be used as a defense to a n allegation of adultery as a bar to alimony.
