Search Results: doesn''t look at me during sex

Okay so me and this girl have been friends for like 7 years. I am a female as well. We've always had an eye for eachother since gradeschool but we never took it to the next level until 2 years ago. We hook up a lot and it is always so passionate. We cuddle also We tell eachother all types of things during sex, for example: I love you so much, you're my girlfriend, you're the only woman i want... you know stuff like that. lol We also cuddle from time to time. Now i have recently revealed to her that i am in love with her. she told me she wasn't looking to date a female, and that wasn't where her heart was. I took note of that, but we STILL have sex and tell each other the same things. We argue like a couple aswell and she always brings up relationship matters, even if thats not what the initial argument is about. for example, she gets upset if i hang out with other girls. and she always accuses me of messing around with other women eventhough thats not true.
We dont usually get upset about dating guys though (well she doesnt). Deep inside i hate her dating anyone although i never admit it. I think she knows that but i feel like she rubs the other guys in my face, like inviting me over when she is with them or telling me how much she likes a guy (note that this woman knows that i am in love with her). I try to support her because i realize we will never be official, so I take on the friend role a lot of times and just support what she wants.
I feel like im putting her happieness before my own. I guess i just want to know if anyone can help decode what this girl is really feeling. why would she bring other love intrests around me when she knows how i feel about her? Should i let these feelings go or should i stick around hoping maybe she'll have a change of heart?
