That's a worst of advice you've given!! Divorce is most disliked halal act in front of Allah (s.w.t) and it is acceptable to practice only in a very extreme scenario. The one above is nothing as such!
@OP: You need to reschedule your work-life balance. The routine overtime you're devoting to work has actually got the right of your wife. Give that time to her and explain her that there is no one else in your life and show her that if you are busy then you're doing your work only. Don't give-up till the time she's convinced. It might take some time.
And involving any elder at this stage would only ruin the matter rather than any resolution. Try to fix things between both of you only. No one can win her trust upon you but only you!
btw.. welcome to the club! (H)
