Girlfriend is really pissing me off and i'm starting to lose interest

Thanks for your advice but the misunderstanding you may have is that she is not a bad girlfriend, we basically do everything else a couple does (kiss, hold hands, oral sex,etc.) in public and basically everyone knows we are dating. She has bought me presents and made me food on several occasions she even wants me to take her V-card.Sometimes i get random texts about how much she loves me. It's just when it comes to going on dates its a different story.
