What Is love?

That is the question...The question that I am not the first to ask... What defines love? Is it the butterflies you get when you see someone? Is it the warmth that you feel rushing through your body when that someone else kisses you? Or are these just the physiological reactions to what we commonly call "passion"...You know I've really been asking myself all sorts of questions concerning love lately which is probably quite normal since I broke up with my first boyfriend a week or so ago (we had been together for 2 years). And then I met someone else and I told myself "you know you can't fall back into your old habits right now, you need to get back on your feet before you enter a new relationship"... But I can't! I wanted to be detached but I'm not... I am constantly waiting for his phone calls and then when he doesn't call me (like tonight) then I am a mess... I am heartbroken all over again and doubting myself "did I do something wrong?" or "am I too clingy?" or I think that maybe he had enough of me that I'm not cool enough or pretty enough... Plus I can't even concentrate, when I'm at work all I ever do is think about him... it kills me, I hate being like that... Before I fell in love for the first time I thought that I was an independant woman but then I discovered that's not the case... I refrain myself to call him too often... I try to let him come to me instead but I have lots of trouble with that which sucks... My life is my life and at the end of the day if I keep living my life through other people I will be the one that's left filled with regrets because I did not enjoy it... Obviously that's not what I want but I don't feel like there's nothing I can do to stop myself from thinking about him... like I try to change my mind but it always stays with me. Now tomorrow I'll go the gym and get a membership since it's been a long time since I've been active... I'm thinking that it might do me some good... I just hope that I did not spoil everything with him because i got involved with him too quickly after my breakup... he's a good guy and I am emotionally involved in this relationship so I know that if it ends I will be heartbroken all over again because let's face it, 2 heartbreaks in a month is more than I can bare...But you know tomorrow is another day so I hope that a good night's sleep will help me see things more clearly...:-)
