<human>: Give me a shortened version of the text

I've been in a relationship with this girl for 3 months and there is almost no affection coming from her.  Anything that we do physically is always initiated by me, and she acts like she doesn't want any part of it.

And I'm not talking about sex either, it can be as simple as holding hands or giving her a hug.  When we're together it feels as if she doesn't want to be with me in a romantic way.  When we watch movies together on the couch she doesn't sit close to me, doesn't want to hold hands or cuddle.  When we go out on dates I'm lucky if I get to kiss her once throughout the night.  When I try and kiss her she keeps it to a short peck and pulls away.

However, when we text each other or talk on the phone she is perfectly affectionate, flirty, and acts how I feel a normal girlfriend would act in a relationship; but again she never initiates the conversation and doesn't try to keep the conversation going if it hits a lull.  I haven't sent her a text message since last night and since then I haven't heard anything from her, she hasn't sent me a text of any sort or tried to start a conversation with me.  

I talked to her about this before and she claims that she's not an affectionate person, is that true? are some people just not as affectionate with others?  If so then why do you think she would be affectionate over a text message yet not affectionate in person? I could use some advice on this
<bot>: My girlfriend of 3 months does not feel like my girlfriend, she never initiates intimacy for basic things such as kissing or hand holding, what should I do?
