Most Helpful Guy
I think the fact that she won't put her arm on you tells you a lot. I would never be with a person who is too embarrassed/ashamed/worried about being seen with me that they won't even touch me publicly. But if you want to be together then you shouldn't feel like that, either talk to her and tell you don't like what she's doing, and keep her hands off others until she gets her hands on you, or just keep reminding yourself that no matter what, she's yours, and only yours. Or my personal favorite just go right up to her, look her in the eyes and say, "baby, I love you, I want to spend the rest of my life making you smile, and I don't give a damn who knows it" then kiss her! Right on the mouth in front of people and lean her down like in the movies.
