pleez help..best friend problems...

me and my BFF have been friends for 9 years but ever since she met my guy friend (who i really like) she's been really annnoying latley. She acts like they've been friends FOREVER when they haven't and she always talks about him when im talking to her. she knows that i like him but she annoys me about him all the time (it makes me think she likes him when she claims she dosen't) she's also been a little controling latley so my other friend said to take a break from her for a bit...i emailed her and told her that and the reasons why and she took it the wrong way and said "i only need 2 tickets for the concert anyways" i don't want to lose her cuz she's my BFF but i don't know what to say..pleez help
and im sorry for the long question!
