Eat three well balanced (referring to nutritional value, not the plate on the table) meals a day and exercise regularly. Running, jogging, biking are some good ones and they are even more enjoyable with a friend or two.
When I saw untouchable I thought the person had leprosy. Regardless of this comedic misunderstanding of your thread title I think that you should probably talk to her and see what comes of it. Judging from your avatar though you aren't that good looking and she probably won't talk to you unless you're hung like a horse... so if you are let her know.
And stop writing in purple. And also if you don't know her schedule you can be like hey are you up for a movie on such and such a date and time and if she wants to go she might suggest another time or activity etc. Like the other person said, worst case is she says no.
Instead of doing a survey look for a credible source of information. Asking us will not provide you with nearly a large enough sample size or any credibility.
Tell her that what she's doing is fucking with your head and isn't working for you (assuming both are true), and let her know that it's over if she isn't going to change then you are history (or just keep fucking her and sever your emotional attachment, but that's not really honest with her and you have to be pretty cold to make it work).
