Your husband is going to be playing VICTIM for the next few weeks while the damage rolls in on him.... this is not the last of it... do NOT ENABLE him...
By this I mean do NOT allow him to put YOU in a position where YOU feel sorry for HIM...
He has been HURTING YOU FOR WEEKS... do NOT allow him to make YOU feel like the bad guy here... HE IS CHEATING ON YOU and has NOT STOPPED despite how clearly you have made your hurt to him... he is NOT to be CODDLED at ALL... this will just allow the AFFAIR to CONTINUE
Let him suffer... this is how he GROWS UP...
Just like a CHILD ... he needs to learn consequences... and when you coddle him you do not allow him to grow up and experience that... you are NOT helping him when you enable his "poor me" behaviour.. ok?
In short, its HIS BED, you have to LEAVE him to LIE in it... he wont' like it, but don't do ANYTHING here... shut yourself OFF from it...
