Just reflecting on how important it is to be reminded of how damaging my "going off" on H is. In some ways it's honestly a blind spot for me, particularly in this situation because I feel entirely JUSTIFIED in going off on H because of the A.
We all may feel perfectly justified in chopping off the heads of our spouses with a sharp axe for their stupid affairs. Does that make it ok? No.
Remember this:
-Do you want to be right? or -Do you want to be happy?
For me, I have had to check my pride at the doorstep. When it comes to saving your M, you MUST keep your pride checked big time. Otherwise your resentments will rear its ugly head and your "Old Faithful" blows right out of your mouth.
It isn't any wonder that H wants to stay the f*ck away from your mouth. Remember the honey vs. vinegar parable??
Starsky, Bond, and others have given you some good advice.
Light, breezy, and confident. C'mon...pull her up from the dark space out into the sunshine.
