Love and Relationship Issues(MY VIEW,MY STORY)

Before i start let me just say most people will agree or disagree with me on this subject but its just my own view of how i see it.Lets define the meaning of love  first 'Love is an intense feeling of deep affection for someone or something'.
However researchers has told us that love actually has nothing to do with the heart but its all a chemical reaction inside the brain.I have found that no matter how beautiful,pretty,hot or handsome you are there is that special someone we always think about before going to bed and in as much as most relationships are for real,some are just in it for the fun hurting the people they claim they are in love with knowingly or unknowingly.
I remember my first crush i had when i was in secondary school,seeing her everyday in class just made my day,i believe love is one of the most powerful force on earth because if u love someone and the person loves you back as much as you do the feeling we have is something we can;t really describe.As human beings we all feel that desire and hunger to be loved by someone and when we find the right person it just makes you feel have that 'butterfly in your stomach' feeling,guess you know what i mean.
However,there are lots of problems in relationships these days which are caused by pride,ego,lack of trust,rumors and many more.
1)I find it very down-grading and stupid when i see boys fight over girls or girls fighting over boys.I remember i did that when i was little and even though i ended up having her i still regret it up till now(i don't want to go into details) but to me i believe relationships are not worth you fighting over someone,if a person wants to be part of your life he or she will be part without any fights or unnecessary stress.Do you think fighting over that boy or girl will make them love you more,my answer is NO!!!! what fighting does is that it makes you look very stupid with no "small sense of pride',it also leads to you being embarrassed just imagine it for a few seconds after fighting then someone walks up to you and asks what is the problem and you tell them 'he or she stole my boyfriend or girlfriend,doesn't that sound very child-ish and stupid'.I can assure you 101% that it makes your other partner you fighting over for looks at you as a fool and it makes them feel special ,think of it,two boys or girls fighting over you even though some people deny it i can assure you that a part of them makes them feel like a superstar.MY ADVICE TO YOU DON'T EVER FIGHT OVER A BOY OR GIRL IT'S NOT WORTH IT.
2)Rumors are one of the main killers of relationships nowadays,don't just believe everything you hear about your partner even though some might be true,i will advice you try your best to find out yourself before you jump into conclusions,don't just conclude based on someone's assumption.What you hear about your partner doesn't make it true unless you find out yourself because some people might not be happy with your relationship.Also lack of trust in a relationship leads to both partners cheating on each other,i think trust is the foundation of any relationship in this world it takes years to build and seconds to destroy so if your partner has trusted you PLEASE don't give them a reason to label you a liar.
I DON'T LIKE WHEN I SEE PEOPLE CHEAT ON THEIR PARTNERS IN A RELATIONSHIP,IF YOU KNOW YOU DON'T WANT THEM AGAIN WHY DON'T YOU JUST BREAK-UP WITH THEM RATHER THAN HURTING SOMEONE'S FEELING IN A CRUEL WAY.
