Search Results: can''t get over him

I like my sisters best friend, we have known each other for almost 6 years and I really like her, and I want to know if she likes me but im getting mixed signals. Whenever she is out at our house I always try to hang out with her and my sister, my sister always tells me to go away and not bother them but her friend always wants me to stay and says its not a big deal. We always laugh and joke around with each other and have a good time. When we havnt seen each other for a while she always runs up and gives me a hug. BUT certian times when she is with my sister she barely interacts with me. We were up at our camp and i had to run to the store and she jumped up and wanted to go with me, we most surely were flirting with each other the whole time and when i said we should pull over in the field and watch the sunset she said she wanted to. But as soon as we got back she was totally a different person and wanted nothing to do with me. The next day i asked if she wanted to go fishing and she said ya, when my sister started to follow along her friend told her she didn't want her to come, we went down to the dock and she was making a fool of herself trying to fish and asked me for help, i did the classic put my arms around her to show her how to cast out the line and she had me show her a few times. We sat and talked for a few hours and watched the sunset and i loved every minute of it. BUT when we went back up and sat around the fire where my sister was she was the exact opposite again showing no interest.

She knows i like her, i have told her. And i know my sister isn't thrilled that i like her best friend. When i asked her out she said she wants to but she cant? And when i asked if she liked me she said its complicated?

Any help please, im just confused?
