You really need to calm down! I think you're reacting very angrily because your pride was badly wounded with the confirmation that H spent some days with the OW. It is understandable that you're feeling this way, but getting all riled up and acting impulsively by texting the OW isn't helping matters at all.
Find a way to center yourself and impose the 24-our rule when you feel emotions bubbling up on the surface. A lot of the times, the next day you feel differently. The problem with those reactionary actions is that you cannot undo them. Don't stoop to OW's level. You are miles and miles BETTER than she ever will be.
Your H is a very lost man who has lost his way...hence MLC. It will take a looong time for him to burn through the replay phase. You're going have to dig deeeeep for patience.
