How do we know we love someone?

What if we are not sure we love  the person who loves us?
What if u let her/him go and later u realize u do love him/her?
Why do we cry for someone when he leaves us ... and he he came back with us We arent sure about our feelings?
Why is love so difficult?
Does love really exist?

maybe we get marry just for not being alone?

Love is not what u want to fell.....love is what u feel without want it

I dont know if i love him ....... but im scared about lose him....

he is a good man and doesnt deserve this.....

but im not sure about us..... what must i do?
I dont wanna hurt him coz he means to much for me
but I want the best for him.....

Once I finished our relationship and he did everything to come back...

to be honest i was destroyed when we broke..... but I didnt have time

to think about us ... coz we came back very soon

maybe i need sometine without him to know what i really feel!!!!

Oh God!!!!! Help me!!!! I dont wanna hurt him but I dont wanna hurt myself neither!!!

Also I know that if our relantion finish I will lose him forever.....

I dont know... I will wait for the time to show me the way
