INTP women in their 20s - what's your dating advice?

Have you got any dating advice for INTP women in their 20s?

I'm friends with an INTP girl that's been struggling with dating kinda badly.

And since she's the "dudette" in the room, she always seem to fall into friendzone category (she's got mostly male friends). She never complains about that, but I can sense she's feeling lonely, and is becoming accepting of the situation in a kinda "oh, well" fashion.

It hurts to see her miserable like that, so I was wondering if you have any tested advice on how not to fall into friendzone, or escape it, if need be.
