On a logical level she wants you to just be her friend, on an emotional level she wants you to fuck her.

What I have done in similar situations (with success) is to tell the girl that we should just enjoy our time together and see what happens. "If you get a a boyfriend, or I get a girlfriend, we can still be friends without sex - but why stop enjoying each other's company if be both enjoy it? Let's just take it one day at a time and see where it leads us, ok baby?"
If she comes over to make out, just play with her tits, kino down to her pants and rub her clit while making out. I'd say there's a 90% chance of you fucking her after that. If she removes your hand, just make out some more and go back down again. Do this again and again until she submits and lets you mount her. If she gets pissed off tell her that you are a man with sexual urges and that it comes natural to you, as an automated reflex. She'll understand. Then go for her pussy again and again.
If it ends with her leaving without sex, keep her as a facebook friend so that you have yet another girl on your friend's list, and don't answer her messages too often, unless when YOU feel like it. That way you are mindfucking her, not the other way around. And chances are she'll understand that you're not interested in having a close friendship unless there is sex involved. She will then probably want a friendship that includes sex. Keep her in your life until you have a small harem of 3-5 other girls (or more/less depenind on how much time you have available for girls). Unless she is one of these top 3-5 women in your life, you then completely stop answering her messages. That's what girls do when they are not interested in a guy, so I guess she'lll be able to relate.
With any luck she'll then proceed to press "like" on everything you post on facebook, write comments on your check-in statuses etc. This builds social proof and is a massive DHV. In fact a gorgeous Croatian girl who lives in America poked me on FB out of nowhere, because she stumpled across my profile and liked it. 20 minutes later we were discussing our sexual fantasies, she wanted us to masturbate in front of each other on SPAM (not gonna happen) and exchange naked photos (that did happen, though). She sent me a pic of herself on her back, with her legs spread so I could view her hot pussy. The photo was taken by her GIRLfriend (bisexual girls rule!).

She now wants to hook up for some vacation fun this summer.

But I'm digressing.
I recently did this EXACT thing with a gorgeous, petite 20 year old bisexual latino girl until I got tired of her and told her that I didn't want to meet for sex dates anymore, and just be friends. She got so mad she not only blocked me on facebook, but actually went to the police to make them call me and inform me that she NEVER wanted to hear from me again!

That girl did NOT appriciate being dumped - especially by a man (she was a man-hater, and enjoyed humiliating men, but couldn't resist getting fucked caveman style by a big, tattooed powerlifter

).
Good luck in taking control over your own life and not letting an ex-GF use you as fucking free therapist.
