Glad to see you're doing well for yourself physically.
I continue to caution you. My W acted similarly:
Quit smoking (which she only did for a few months), saw a therapist, recognized she was depressed, recognized she wasn't herself and needed help, read books on self help, was kind to me, reconnected with children and her mom. I thought for sure she was coming out of it. We were 1 day from withdrawing our divorce from the court. I was certain affair was over, then on her birthday she starts to reconnect with OM on a deeper level.
THEN, she used health insurance to get tubal ligation, which she never wanted before, accrued almost 20k more in cc debt, had a burner phone to continue affair, did not look for work while claiming to go out on interviews (guess where she was going), likely started to use drugs, used me for extravagant vacation (while texting OM as I slept next to her).....then came BD 2.
A few private investigator reports turned up things I never though capable by her--all involving OM as well. THEN came a catastrophic downfall involving burning bridges with everyone who loves her--friends, parents, siblings, children, etc...I am not sure she has even reached rock bottom yet. This is all 8 months post BD1.
Please, please keep your guard up.There may be a few brief times of clarity and then BOOM--right back into the tunnel. When MLC is over, you will see long term consistency and she may not even recall some of the things she did or was thinking. The situation is very likely still on thin ice. Protect yourself. I would advise checking credit reports as well.
