same stuff happens with my girl, shes naive to the fact that these guys like her. I'm good enough to spot whos in the friendzone and whos not, so far I haven't had any problems. Theres guys who literally text and fb her all the time, the problem is that theyre afc, and she will try to be nice and say stuff like I'm busy, or no I cant this weekend. I let her know, to an afc I'm busy means I'll try back next week, so shes been more blunt about it.
The real problem is deep down every girl is insecure and likes attention (doesnt matter if shes a 1 or a 10) she doesn't want the guy, she just wants to be wanted. Mix that with an AFC that just doesn't get it. You get problems... huge ones.
My only solution is push-pull, but thats really the basis of every relationship.....
I emotionally punish her will the pull part of it. were both pretty affectionate towards each other, and have awesome chemistry, so even without being all over each other were still best friends. so i pull back emotionally, I'm not talking a freeze out or anything, because we still have amazing conversations, and have fun. I just don't call her baby, and all the cute things she wants to hear. Its funny because she gets so confused because we'll be having so much fun doing something or we'll have like a long conversation, and she'll randomly be like "you haven't called me baby at all tonight

" I pretend like I didn't even notice and say something like "I think I did earlier, I don't really think about it when I call you it, it just happens." Then it goes back to normal,
even though shes confused about it all after a while subconsciously it sinks in that its a result of that. One time she was crying when we were arguing and she was like "I'm sorry I always push you away, I don't like when you don't call me baby because of those guys that don't matter" which to me sounds like success!!
also during this I kind of change my body language, I still hold her hand and stuff I just don't kiss her on the forehead and goofy soft stuff like that.
moral of the story with push pull, and problems. ACTIONS SPEAK LOUDER THAN WORDS. Don't say you have a problems with it, subtly and confidently show it (without getting jealous)
NOTE: I've learned in past relationship, don't completely shut her out, and run away. She'll only run to other people. Still be there, at least enough to let her know youre not leaving, just don't reward her
btw I know this is pretty detailed, this might not work for every girl (but it should for most because theyre insecure....) I just know my girl and what makes her tick.
speaking of this type of stuff, check out Anthony Robbins "ultimate relationship program" its weird because alot of pua stuff correlates with what he talks about with what partners want, and need. Alot of stuff will make sense, and you'll see problems that you can relate to.
