Search Results: arguing with my best guy friend

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?

I'm bisexual and this year I've had a girlfriend and a boyfriend.
I was seeing the girl for several months. During that period our mutual 'friend' kept interfering and causing bother between us both. This caused us both to argue a lot, I had enough.
Whilst I was only seeing this girl I met a guy whilst out drinking with friends. We got on pretty well, we went on several dates.
I was still seeing the girl, eventually they both said 'you have to choose one of us'. I wanted the guy because I 100% felt nothing for the girl due to all the arguments and drama our shit friend caused us.
Because I found the guy and she knew I liked him she kept constantly asking me to be her girlfriend. I ignored her for over a month and then eventually she pressured me into a relationship. We lasted three days and then I dumped her, I couldn't be with someone I felt nothing for.
I told the guy exactly how I felt about him, we was going well.
When I wasn't around the guy he made a load of nasty lies about me, my best friend told me (she was in the room whilst he told a load of lies about me). I then dumped him and guess what? He went around telling everyone I cheated on him when I 100% didn't cheat on him.
I didn't properly speak to him after that for over 2+ months.
We spoke in June and I forgive him for being a compulsive liar. We was going to get back together until he kept lying about my best friends boyfriend. He kept saying my best friends boyfriend was saying a load of lies about me, I confronted him and he was so confused because he said nothing about me. That was my final straw with the douche and now I've 100% washed my hands with the compulsive stupid asshole.
Have you guys had any failed relationships in 2015?
