Love and everything else??

In some events that just happened in my life I can't say I'm strong but I'm trying my best to be brave not only for myself but for evryone I love. People may see me as a very jolly person but really the smile hides all the pain, insecurities and hurt that I'm feeling. People makes you happy and at the same time they hurt you til you cry a river. This year is one of my memorable year. Why is that?? Trials overcome, truth covered by lies revealed, weakness turned to bravery; all that and more makes me very proud to say I've grown and now know how to fight for my right and to give up things that are not meant for me in the meantime. I can distinguish the difference between hope and expectation, love and lust, infatuation etc etc. I know I've grown to understand the ups and downs of having a committed, NSA and Long distance relationship. When you are in a relationship you tend to overlook the side of your partner and tend to do things too much and sometimes its not enough. Suffocation, insecurities, jealousy; these are some of the reasons of breaking up for me. Girls who become more demanding, more sensitive and more clingy tends to suffocate their partners and vice versa. Guys who diss off conversation, doesn't listen, and letting their partner feel unimportant makes their partners look for another and vice versa. Now, I got a question, what's the difference between important and love? I think from my point of view, when you say you love someone that person is also important to you but when you say that a person is important to you, there's limitation to it. Maybe a person is important to you because he or she might have done something great to you or maybe he or she likes the person but don't love em. I can't explain further what I know about love etc. I'm not an expert about it who is anyway??
