Feeling  the feeling of Love I have found it very challenging (a good challenge) to Keep feeling love. why can't we feel love all the time.  I believe it is because we are conditioned, if you will, to expect something back when we love, whether it is love in return, money, friendship, quid pro quo. We place a condition on our love.  We started out as naturally loving beings but, sometimes that love wasn't returned or the other person wasn't doing their job for us.  So we made our love conditional. Getting something in return.  When i first started dating I fell in love quite easily.  My relationships would end with the other person saying you are smothering me with your love. I believe I was just loving and the other person did not have the capacity to accept that love.  In reality there were times I remember hoping the person would love me back as much as I loved them. They didn't have that capability to do that. It's like giving a gift.  Sometimes it is wanted and appreciated for what it is and sometimes the other person feels an obligation to return in some kind the kindness you have shown and sometimes you expect to get something of equal value in return.
What we don't realize is the love we give does not have to be returned to us.  It can be given to someone else to keep the flow of love moving so it will not stagnate. It will eventually come back to us perhaps not by the person we gifted but, from someone else that was gifted by another.
