Relationship with Liar or Honest

I have a girlfriend, who loves the word "First"...
I always lied to her, I always said that she's my first and she looks like happy hearing all those things...
but you know, I lied, I lied to make her feels so comfortable...
is this right ??



Then I heard her story, she tells all her story...
and in the flow of the time, I knows her secret...
she think that I'll think that she's weird and will leave her...
but no, I love her more than her secret...

Then, I suddenly think that she will accept my past, cz it's already past right ??
and I tell her all about me, so she knows me very very well...
but her responds is "oh, so I'm not your first"...
she's very very disappointed and not making that happy face again everytime I do something...
Lying all the time is not right, but tell the honest is more than not right...

This is between lie or honest, so for you guys who read this story...
maybe there is something that you shouldn't tell ur girl/boy about, you should really have a secret that no one knows...
but for me, if you tell a person like me your secret, and he/she is the only one that knows it...
they will really really love it, why ?? cz they're the only one who knows you well...
different people, different personality huh ??
