hello girl pls do not lead the poor guy on? from my heart i feel
for the poor guy who's going to be devastated when he hears that
actually you do not love him at all. and from the start you 2
started out as if everything was fine, those "i love u, u love me,
we are happy family" types.
but in actual fact it is only him that is doing the loving. you
play along and induces him into believing that he struck gold and
you're his one and only. NO. this is not the way girl, please, save
this poor guy from his future agony. tell him now, tell him
straight. dun keep for him to sacrifice himself more and get deeper
before you break the truth to him. he will be in deeper pain.
do it now. pick up the phone
the worst thing to do. is to give people false hope in a
relationship. 
my 2 cents
