Married fast? Too late? Completely stuck :/

[Complex]

What do you wish to accomplish by giving her this letter?

Intention of the letter is to make her feel I really understand now and that I'll move on with or without her. Then I basically want to go dark a bit and let my actions speak.

Ok, sounds like everyone is aggreeing on it to wait until WAW does the first step. Man this is going to be hard. I agree the letter sounds like hidden blaming.
I did the mistake of letters before and it didn't help. I'm glad I'm here!
