About the LETTER OF NO CONTACT.. my goodness.. hasn't that gotten to be bigger than anything! That mess is his to clean. The focus on the symptom rather than the cure.
Step back.. realize your anger, see what is and isn't healthy for you.. and go back to what works. One tiny step, not the marathon sprinted.. a nibble, not the all you can eat buffet.. a nod not a roll in the hay..
Get help for you... cause you've done lots of work on a broken heart.. and I wanna see the beauty of your healed heart flowing through!
