How can ah 21 years old yound man,can come out of a relationship!wit some one who he love?

Why would you want to come out of it, if you love a 21 year old woman, unless you are under age, not sure how old you are....You speak of coming out of this relationship, and it seems like you have doubts, irrespective of love. In that case, it would be a good idea to take a break from the relationship, tell the person you love, you need some space to think things over, and do so carefully.
