The best rule I have heard for determining your acceptable dating age range comes courtesy of Randall Munroe:(Your age)/2 7 = lowest acceptable age Or,*2 = highest acceptable age For a 28 year old, this makes your age range 21 - 42.
My friend who is 36 is dating a man 9 years younger than her and I have a crush on a man probably about 15 years older than me.
On average they just aren't going to be at my level regarding a whole bunch of life aspects that require another eight years of mistakes to achieve.
Not at all Im 16 years old and dating a 28 year old and he is the sweetest person ive ever come across.
Mind you though, I have always been very mature for my age and have always been mistaken for being around 20. When the 28 year old graduated school the 18 year old was in third grade.
You need to go into this aware that you're probably not her eventual partner.
