I lost track of your sitch after the initial response but just caught up.
First you are NGS to the max. You will not nice her back. So you need to stop. Institute changes in NMMNG. re read it if you have to.
Second, you need to fix your signature. You didn't start LRT. What part of LRT has you offering to cook for her? Has you initiating R talks? (Yes asking her about communicating better is R talk)? Has you bailing her out on the rent? You aren't even DBing at this point let alone LRT!
Praying with her is pressure. LW is right to an extent but stop praying with her but keep praying for her.
Pressure will pressure her out the door. Pursuit will have her run away faster than anything.
Why do you think she texted 4 times while you were in the store? Could it be because since BD you respond immediately? Not responding right away is not pressure. And her reaction was to come towards you. That's what 4 texts are. That's how this works.
Also don't be so sure you blew up the affair. Cheaters are great at , after being caught, becoming even more covert. Business trips are one of their favorite ruses. Not trying to make you panic but her behavior is that of a WW that still has her attention elsewhere.
Take this time to do self reflection. And do the studying on DBing. It is your only hope for success at this point.
