You still have BP notions of love (I guess we all do to some degree) but you have an open relationship, so there is no need to leave your wife, you are free to plate as many women as you want should you embark on a quest to look for this 'true love'.
Do NOT let your wife know about your successes with plates. The marriage is open, she has it easy now, you will have it easier later, once it becomes more difficult for her and easier for you, she WILL try to put an end to the openess of the marriage.
Do NOT let your wife know about your successes.
Leaving her also opens the door to getting divorceraped and it sounds like you are not sitting pretty financially from your previous trainwreck.
What I would emphasize is that she has given you sons and they are still young, you have this unique opportunity to provide them with a lens that is not fogged with bluepill dogshit, provided their mother does not take them away from you.
Scower TRP material for advice on raising sons (there needs to be more written up on raising children), I dont believe the pill should not be administered to young children. Wait until they are ~13 before you slowly unplug them.
TL;DR you're waifu a shit
