Not to minimize your situation but hopefully to make you feel better, my H slapped down a big retainer with a lawyer who sent me a letter (with no warning from H) that H wanted to end our M and I should have my lawyer contact him. That was a month ago. If anyone saw us now they would say "what a happy couple."
I know it's hard but just try not to think about tomorrow. Just worry about today.
