I need Opinions please!?

So me and my Girlfriend had sex but she is more of the wham bam thank you mam. I like foreplay but she says after 10 minutes it gets old. She used to like kissing, holding hands and loving on one another within the first week and now she says she is not the public affection type, but yet in the same breath she isn't in seclusion either now?? I talked to her about it but I get the feeling she really isn't listening to my needs, I mean how can you be a couple but not show affection to one another? Even when we watch shows at her house she doesn't hardly sit next to me. I had a candle light dinner for her and she turned on the lights? I was like WTF? Am I looking to deep into this or is she just wanting me for sex and not an intimate relationship? She even threw out to me the "Are you just wanting sex in this relationship? (booty call)" This is so not the case I just like to show affection and can't quite understand why now she doesn't. We are going on the 4th week now and I am not sure if I should just end this or not or let it ride a bit longer to see if it goes back to like week 1 was with the playful kissing and intimacy. So I need Opinions on what to do.
