My head is literary spinning. So i'll try and explain the situation the best to my ability.

I've been dating an HB8.5 for almost 7 months, tomorrow will be our 7th month together. Technically we're still dating, but I know I need to end it. I've been unfaithful to her, possibly due to the way she acts, and she has been absolutely incredible. She buys me things randomly, she sends me cute texts every time I don't reply saying how much she loves and misses me, my friends wish there girlfriend acted the way she does. Every time we see each other we make it two steps before we're ripping each others clothes off. She pays for things, both of our parents expect we'll get married and our perfect for each other.

Basically everything a guy could ask for at 17 and yet I'm consistently annoyed with her and don't really have those 'she's the one' feelings. I know it's time to end it, I just have no idea how.

Plus, I don't want her to know I was unfaithful that's just like putting a knife in a open wound, no reason for her to know.

So how do I end it with someone who has been so amazing and perfect?
