So if you have history you might as well have asked her to explain herself.
I would've simply replied "Any particular reason you feel this way?"

I mean if you're gonna say "okay" and not give a fuck, then you genuinely must not give a fuck. But you obviously do since you wanna keep dating her.

I still don't understand the prerogative of "it's either a relationship, or friends".

Who said anything about relationship?

Frame it? there's no need to frame it as if she's jumping the gun, because she is jumping the gun.
Who the hell thinks relationship after two dates?

she said it was because she didnt want a relationship.

And ex probably came into her life man. I wouldn't stress about it. You can definitely pull again and again so long as you don't get wrapped up in this losses.

On a side note though: if a chick gets the vibe from you that you will be devastated(come running to a forum) if she leaves you or friend zones you and/or that you will still want her if she leaves you or friend zones you, she now has the power to play that card if she chooses. Meaning you will be on the back burner if someone else comes into her life that she doesn't have that power with.

She has you where she wants you; desiring her without her having to give you anything you want in exchange. Why give you what you want when she's already winning without doing so?

Should I say nothing?

When you get to my status (not even that advanced) you will find you don't want to be in a relationship with a women. I just want to have sex with women. A relationship means I am on the hook for more shit I don't want to deal with.
