You can't start loving someone who is not done loving another...how does it really work? How does what work? LOVE.
Many has over the years wondered about what is love and how it does work.. how does one know if it is real or fake.
The realness or fakeness of love has lead to a mix reaction and definition of what love really is and how it does work to show that it's really love and not something out of the blues. One cannot say for certain that this is what love really is or how it works, this is so because many scholars has written books about love in which they state principles and steps on how to go about love.
This books has not really define what LOVE is because most people still complain that after following and practicing the principles highlighted in those books, they don't understand LOVE why others give positive report about love.
This chain of different reactions can be linked to the saying "different strokes for different folks."
For the fact that Mr. A and B read and acted everything inherent in the book does not mean it will work for the both of them.
People feel LOVE in different places and situations but what matters is, what role did you play in ensuring that what you feel last? What positive meaning did you give to it? and how did you envisioned the love to be in the near future?
On the other hand, the person you feel the love towards, what was his or her contribution towards maintaining and sustaining the love? Did they feel the same way you felt for them? Or was what you felt for them higher than what they felt for you...vice versa.
Most of all, did they share the same vision with you?
Many people who have felt LOVE but it did not turn out the way they visioned it to be turned out to hate LOVE, to ask questions like, what is LOVE? What did it really feel like? How can you tell if it's for real or not? this questions bring people to the point where they evaluate themselves and their love life.
Hatred towards LOVE have made most people to give up on ever finding or showing real love.
But why people focus or blame LOVE for one reason or the other they fail to realize that the LOVE might not be the issue rather they or their partner might be the ones holding on to something that is not really there or that doesn't exist anymore: which has made it difficult for them to really feel loveand be loved.
The inability for one to let go of something that was very dear to him or her makes it hard for them to move on to something new.
Now, a situation where Mr. A loves Miss B, but miss B does not really feel the same for Mr. A, simply because she is still holding on to some other person in her heart and is hoping to get back to that person.
This disconnection of feeling becomes a problem for Mr. A who is really the one feeling the hit of the LOVE. If this disconnection goes on for a long time, it's leads to a break down in the feeling and love of Mr. A for miss B and it's in turn give love a vague meaning. This might also make Mr. A not to want to ride with LOVE again and when some other person shows him real love, it might miss interpret it because he too is holding on to what he felt for miss B. 
This can be seen in the world today where you love someone but that person does not really feel the same way for you. It might be that the person love you for your money, fame, beauty and so on but when it comes to the real love, they don't feel it towards you instead they feel it for another person.
Take those things away and you will realize that the love is not for you persay but it's just on those things they see around you. Love cannot be balanced if the person you are loving is not done loving another. He is not willing to let go and does not feel the same way you feal for them. Do not start loving someone that is not done loving his/her ex-wife, husband fiance, boyfriend or girlfriend that they are not willing to let go or are not ready to share the same feelings or emotions with you.
Else there will be a break down and you will pour all your ANGER at love without considering the obvious. Of a truth, the human love is not perfect like that of our father in heaven but we can come close to making it perfect when we find and lovethe right person that feels the same way we feel for them.
Loving the right person makes love a beautiful thing despite the challenging and trying times the love will still stand and come out even more stronger. But loving someone that is still loving another causes so much pain and cannot stand the test of time. It will also lead to the people asking if it is for real or fake, how does it feel and so on.
This questions arises when you start loving someone that is not done loving another but the reverse becomes the case when you find LOVE with the right one. You will know what to do, how to act, what you feel if it's for real.
You will be able to face what ever issues that comes in the course of loving that person. This is made so, because there's a connection between you and that person you love and you are being loved in return, the feeling is genuine.
Love and be loved then you will get all the positive meaning of love but love someone who is still holding on to something then you will get all the vague meaning of LOVE.
