Down and out...need hope.

[DownNotOut...yet]

"You're finally giving her everything she's asked for, but it's too late." Another line directly from the script. You may find initially, the better you do, the more pissed she will become. Don't be spooked. She may be trying to resist letting you back in. It was all nice and easy when her plan of leaving was clear and clean. You seem to be doing some things right. The seeds of doubt may have been sown. Also, it is possible that the better you do, the more she will shout she is leaving.

"Why would you even love her" could be her trying to project her issues on to you. Or spin the situation to make herself feel better. While killing myself to be a better husband, my wife told me I didn't love her. Another pretty common line to hear.

If your wife wanted sex, be glad she wanted it from you. No matter what the reason, you got some sex...and your wife chose to have sex with you as opposed to anyone else. Maybe she wanted to be close, maybe she just want to get some. Either way, a totally positive sign. I went for six months of listening to my wife say she would rather do a stranger than me. When we finally did have sex, I asked if this meant we were on our way to being better. She said, "no, I was just horny." So your experience is again not unique. There is worst one could endure in this process. Be happy, you got laid!

Very often it seems after sex or after a nice, pleasant, perhaps loving day/experience, they will withdraw for a while. Don't get scared, don't ask, don't push. Act as if all is great in the world.

As I read your post above, it seems you are still challenging her. Asking her if "it was worth it" and pointing out how her stress is chosen. Try to listen and empathize. Try to see things from her point of view. Two ears, one mouth. Listen at least twice as much as you talk. You are not in a position right now to argue your case too much. Better to demonstrate with your actions than try to convince her with words.

What would be in this long letter you are thinking about? What is the purpose of the long letter? Depending on the contents and tone of your letter, it could be seen as pursueing or pressure.

Stick to "finally giving her everything she's asked for", that seems to be working. You're lucky, she talking. Some folks are told there is nothing they could do. You have a target to aim at.

There is totally hope. May the force be with you
