She's not affectionate. What can I do?

My girl lol.where do I start. Well me and this girl met a few months ago at work and we did the whole friends thing for 4 or 5 months, then she pulled the let's get serious trigger which surprised me because I never thought she would want to take things to other levels with me. Things between us are good the only thing I don't like is that she's not really affectionate enough with me, I always have to be one to hold her hand and etc. She has admitted to not being a affectionate girl and I told her that I would like to change.

At this moment she has been away from me almost a month handling somethings out of town. We talk on the phone every once in a while but text alot, sometimes I text her just to let her know that I miss her and she will reply back with a happy face or something of that nature (which is better than nothing from her) but the thing is that I say what I feel and I know when I say things like that it makes feel good. But she doesn't say it back to me which kinda hurts sometimes, there has also been cases where I might go pick her up or meet up with her somewhere and she doesn't give me a hug, kiss or anything. If does do it that surprises me alot, but I really don't know what do here I want her to show me that she cares about me like I do her. Any suggestions.
