why do we fall in love  

we fall in love b/c we love that person deep in our hearts.But sometimes,the person don't feel about us the way we do and than we wind up getting our hearts broken.The best way to avoid that is to check to see how much they feel about us,how they feel about us deeply.
Easier said than done,yes i know,but with the thoughts of that than we can overcome our hearts being broken.
I've been like this before,and much to say,i have been hurt before also.
But,i've learned not to take people serious,and not to take relationships too fastly.That was my biggest problem of all is falling for them too fast.
Now,i just let it go day by day and hope for teh best in the future.

I understand how you feel because I'm going through the exact same thing. You're not alone.

I thought we would be happy together, but now it seems I'm not the one that makes her happy.

I do not believe in falling in love. I read this book about love and falling in love and I think its correct (The road less traveled). Says there that "one of the most misconception about love is that falling in love is love or at least one of the manifestation of love". Well, its not and I agree to the book and the so called falling in love is not love per se. Ahhhhhh... My head is turning... maybe this is love? Hahaha. Seriously, you will know if its love if you are committed to that person no matter what she/he. After marriage and you feel you dont really like her/him and you chose to stay... that I think is love... no conditions...

In fact, there a number of people who fall in love do not because they love each other. Maybe they just feel lonely and desire someone to accompany.

Of course, I do not deny all of the lovers. But every time you say "love" doesn't mean you can sacrifice everything for your companion.

We fall in love because we have to, we cannot fight those feelings. I did my best to fight my feelings when it came to the man that I love, but I could not do it. When love comes, it is very unexpected. I never expected to fall in love, but I did.
