your children already teenagers, they dont need your guardianship anymore assuming they're almost 18 and able to work.

your wife since the beginning days you met her, may not be a good candidate for long term relationship. And it sucks for you as a married guy cause you've never put in the time to learn about game and communication skills

we outsiders would project she can be a liar/hypergamous/been cheating behind you long time, we have heard a lot of scandalous stories of a 'busy' female who gets a lot of cock attention because she's too stressed with her work

Its either you divorce her before she divorcing you. You've to reclaim back your strength instead of stuck in this mud
