Well I have been threw this exact same thing... I have come out victorious.....
Yes its always going to be there, that is the simple matter of fact... Now let me be absolutely firm when I tell you are you sure you want to invest in her and your not doing this for hit it and quit it.
if so, please leave her be because if you do so and make her one of your conquest as such.... She is probably never going to open up ever again or at least things will become much much tougher...
Now lets say you do want to get her... How would you do it ?
1) As of now, it seems you have broken off with her.... Contact her back again, give her a phone call and ask her hows shes doing etc.. Keep the conversation very light and fun, avoid deep subjects.. If possible put in some innuendos so that there's a hint of sexuality {avoiding the friendzone}
2) Make sure you have all the three rapport with her.. Light, wide and deep.
3) Plan an hangout, lets say somewhere fun and exhilarating preferably half day or full day. lets say a theme park. Whilst making her the happiest girl on earth, make sure there is a certain degree of physical touch - keep to areas of lower back, hands, and head if arises.. stay away from her highly sensitive/sexual areas.
4) By now she should be contacting you on a daily basis, make sure that you show that you have interest towards her.
5) After a certain period of time, you will start to see that shes starting to get more and more open and lose to you.. Utilize it and start getting physically playful without ever going overtly sexual/romantic
6) Hug her, hold her, tell her about her beautiful hair, how soft it is, her skin etc sniff her neck and ask her what perfume she uses whilst sniffing, go close to her lips but don't kiss her even if she tries to unless she really leans in for the kiss
7) Drive her mad by not giving her the kiss, after somewhile shes gonna start telling you that your too shy and that you cant kiss etc... tell her you can, but continue doing so {dont give it to her} maximum a peck

Then drop the bomb on her and ask her, "Im sorry but I just realized this, that me and you are doing so much to one another but we aren't even dating" "I don't know if we should continue or not"
9) stay away from her for 1 - 2 days and then tell her, you cant keep her out of your mind no matter what you do. She should also reciprocate the same and if she does then later tell her that you love her..
10) If she doesn't respond or avoids the I love you part.... Go back to fun, physicality and tempting and the try again.
By 3 tries, you should have bagged her......
This took me a total of 4 months to execute, but she tells me she loved me from the 2nd month itself..
May you win her over bro, go get her.
