Girl, help me with facebook chat.?

I am chatting with a girl on facebook. Its going smooth from a month...

But sometimes she talks about sex, i discussed that topic like in a different way.

We r gud frnds and we don't know we like each other or not. But we talk cool, just frnds i think. There is no attraction yet.

Today also due to some reason she started talking about her calves... I replied gud. She was saying that she has a little big calves, so she is stitching her pant.

I said ok, do it...

It will fit u after that.

Then, she didn't reply.

Did i do something wrong? I don't think so.

Is she trying to seduce me? If i ask "are u trying to seduce me?" will she laugh, or take wrong meaning...

Am i being too good? What should i do? Girls, pls help me to understand this. I am just confused.

We r having gud time with each other and i don't want to break it.
