I don't really think that an age matters as long as you're within legal range. But some people like to use this as a reference:
Take your age. Divide it in half. Then add seven years to that. What you get is the youngest you can date.
What is an acceptable age gap in a relationship?
Well, if you're an adult, age has no meaning. If you're willing and your partner is willing, love is all that matters
the acceptable age gap is 2 or 3 years but no more than that sweetie
As far as love is concerned, there is no age bar to it! But if you want it for a long term then it is better to have a maximum of 3 years age gap.
