There is no formula.. It is a case by case instance.. I have dated older and younger women.. For some reason, the ones involving younger women seemed to last longer..

It is all about feeling safe, secure, and loved(both directions).. Age is not/should not be the mitigating factor in ANY relationship..

I will state that if puberty has not been reached, then the person has not/is not grown up enough to understand what a relationship truely is...

At my work, i have seen many variances in the ages of couples passing by.. some have older males, some older women.. many close in age.. The ones i know will last longer are the ones that seem happy and comfortable with each other..
