Never get a girl who wears pink all the time; likely she is a cupcake.
Girls never get guys who ride around on their bikes or scooter or watever all the time oblivious to their own existence.
Some people are committed to live every moment to its fullest and will do what they can to enjoy what they have while they still have it.
A woman who belongs to that category should enjoy your relationship with a young guy and all its benefits and thrills, while recognizing that it will eventually be over due to no one’s fault.
I don’t think any woman can find an absolute and unequivocal answer to this question, and I frankly don’t believe that such an answer exists, as it would heavily depend on that specific woman’s goals and needs at that specific point in her life.
