As a male who is probably past that stage, I don't remember anything like that happening.
I believe the "mid-life crisis" is BS. Some men just use it as an excuse to try and relive their twenties, and then dismiss it because of the "mid-life crisis".
No man, no matter the excuse, should put their marriage in jeopardy with cheating, drinking, etc.
If one does, it is not a crisis, it is self-indulgance no matter the consequences, and highly disrespectful of their wives and families.
Kick the bum out!!
