Really getting tired of the Ups and Downs

I used to talk about Becca a lot. You remember her right? Well everything is going to hell as far as I'm concerned.

I just don't know what to do. Being friends with her is the only familiar thing I can really hold on to. But I don't want to hold on anymore. There are just too many complications. I barely get along with her anymore, she never pays me any attention when I am around her. She won't let me anywhere near her, because apparently she needs her space. Which normally I would totally understand. I get it when people just are comfortable with being close to others. But Becca doesn't need space from anyone but me.

She hangs all over guys, even she admits it. And she doesn't have a problem with Kate laying all over her. She doesn't care about anyone being near her but me. When I spend the night we sleep in the same bed. Me in pajamas or my clothes, her in her bra and underwear. With only a blanket between us. And yet she is constantly telling me to scoot closer toward the wall. She wants me to basically stroke her back and arms while we lay in her bed talking, but I'm not allowed to give her a hug unless it was her idea. Seriosly?

I am pretty sure she doesn't make Kate do that. Or any of her other friends for that matter. I mean, the arm stroking is something I used to do. On my own arm, it was a subconcious thing. When I was bored, I would trace my vein in my left wrist up and down. But after my accident I couldn't do it to my own wrist anymore, because I don't like to do that to my scar. So when my friend Court asked me why I didn't do it anymore, and why I did it in the first place I did it to her arm to show her my reasoning. It's just a comforting thing, and it used to make her arm go numb. :)

Then, back when Aj and I were still on speaking terms and we were comfortable near each other, we were sitting in a car and he was in the back leaning over the back of the seats. I got bored and started doing it to his wrist, he didn't care. But Becca saw me doing it. Then she asked me to do it all the time. I don't know why she always asks. She describes it as tickling her. I find it kind of wierd.

So anyway, I don't know why Becca is like this with me. I get the feeling she thinks I'm a lesbian. I mean, so many other people think that I am. I don't know why else. But whatever the reason, I don't want to be around her anymore. It's just upsetting. She doesn't care.
But still, we've been friends sine 5th grade. How am I supposed to block her out of my life? She was like my sister.
