I prefer the term "Midlife Awakening".
Essentially everyone in my opinion reaches a point where they realize they have more years behind them than in front of them.
This may cause the individual to reassess decisions they've made in their life. This will vary from one person to another. Someone may reach the conclusion they never cared for their present career, another person couldn't afford their "dream car" when they were younger but now they can, while still another person may now feel they "settled" when they got married.
Whatever it is I believe both genders reflect on their life choices.
It's only a "crisis" for the other people involved with them.
Some people don't really figure out who they are and want they really want until later in life. Very few dreams have "expiration dates" stamped on them.
The whole notion of "bucket lists" could be seen as "midlife crisis" to some folks while to others it means spending their remaining years chasing their dreams. Radical changes scares people who are comfortable with you as you are or how things are.
We're either "growing together" or "growing apart".
Communication is the GPS that tells us which one it is.
Ultimately you are responsible for your own happiness.
Life is a (personal) journey.
Know yourself, Love yourself, Trust yourself
In order to know real happiness if you have to be true to yourself.
If something doesn't "feel right" to you it's probably not right for you.
Reflecting on one's life and considering changes isn't a gender thing.
