What does it mean when a girl loves your jokes?

[Greateye]

Is this already stating that we're already friends?

Why would they say this out loud enough for me to hear it?

Is this a form of attraction or a compliment?

I've heard from some girls that I know that say:"that's funny, I love it".

I don't know if this would also help but these 2 girls had shown signs of the following:

Looked at me from a distance, made jokes with me, biting her lips while looking at me, tried to cheer me up, etc.

Do you have some substantial reason to believe that she wouldn’t be interested? These seem like pretty straightforward “yes” signs to me.

She wants you to ask her out.

You're one step closer to getting laid.
