Anyone who is "undecided" about which person they should choose is not "in love" with either. If you're "in love" the decision would be very easy to make. This assumes a person is selective about whom they choose to date based upon their own "mate selection" criteria.
The goal is to find someone who shares your same values, wants the same things for a relationship that you do, naturally agrees with you on how to obtain those things, and last but not least there is a (mutual) love and desire and for one another.
Like attracts like. People who love one another and naturally agree on the important things in life tend to be happier and stay together.
Who knew?! :)
Never separate your mind from your heart when making relationship decisions. The purpose of the mind is to protect the heart.
"Never love anyone who treats you like you're ordinary."
