Falc, step back and look at what you have posted.
This journey is a one-sided trip, with you doing all the pleading and grovelling. Even though you try to do the 180, it seems to be a half-assed attempt.
Why do I say this? It is not to hurt you, but looking at your texts objectively, you are letting her control you. You are the one that is keeping yourself in misery, by using hopium non-stop.
You are Hoping that she will come back to you. You are Hoping that she will love you again. You are Hoping that she will turn around, and be the girl you fell in love with.
Sorry to say this, but Hopium addles the brain. It makes you think in strange and illogical ways, and it is addictive, as you will need to use more and more, until you get the desired outcome. If the desired outcome does not materialize, you add more, until you are completely spent.
Wean yourself off this. It will be a real downer, and you will probably feel awful trying to get over it. A Hopium user is unattractive, as they reek of desperation, and desperation never wears well on a person.
Step back, look at what you want, truely. No, the end point is not getting your WW back. That would just be a by-product of what you want in life.
Your one true goal, as a lot of other posters have mentioned, is to get out of Infidelity. This will lead on to a better, less complicated life (unless you are also addicted to Drama in your life). The tried and true rule of K.I.S.S still stands.
The texts that you have sent still give her some power over you, as you are responding to her questions, and not you directing the conversations. You want control over the conversations? Don't answer. Don't keep in contact, as there is no need to (since the joint bank account is already empty, and you have already given her the answer why that is so).
If she is truely remorseful, her further contact to you will change in tune, from 'her'-centric messages, to ones that are more empathic in tone and content.
So, to end this, ask yourself this question; 'why am I so keen to win back someone that is causing me all this pain?'
