Aj, everything she is doing right now, my W did at the beginning. She's acting out of fear. This is your chance to handle it appropriately. Stay calm and do NOT respond to any angry texts. They aren't worth your time.
Also, make sure to save every text that she sends. Do not delete anything, and check your phone settings to make sure they don't auto erase after a certain amount of them or a certain time. I lost some doozies from the beginning because my phone purged them after 50 texts.
We are all here for you buddy. This is going to test every ounce of strength you have. Lean on us.
