The feeling will become a Physical Love which is base on sex only and if you shut it down, it usually leads to manipulating. Saying things you want to hear so that person can get what he wants. Relationship that is lust base will always die, because lust will only satisfy for short period of time. Then Love these days is not the correct way Love goes. Love these days is like wanting a car so bad and after you get it, you enjoy it and as time past you don't feel the same about it anymore. So you start wanting something else. This is the wrong type of Love. As Guy, I would make him wait and see if there will be trust, and true love which should lead to marriage.
1 Corinthians 13:4-8
New International Version (NIV)
4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away.
