<human>: Essentially, my girlfriend suffers from depression and such things, and to make matters worse, her family is falling apart. Needless to say, she's been clinging to her best friend of nearly six years, rather than her boyfriend of one.

I find myself stalking her Skype to see if she's online after she already told me she couldn't talk. I lose sleep wondering why she keeps me around if I'm of no use to her. I Shouldn't do these things, but I can't stop. 

What's wrong with *me?* Why can't she come to *me?*

I've been incredibly harsh with her lately on account of the pressure, and I think she's starting to get fed up. How do I stop and acknowledge that she needs him and not me? 

Is there a chance she's manipulating me? 

He's a nice guy. He really is, and I love him almost as much as she does, but I don't trust them. I need help being normal, and shoving this into the back of my mind.

Also, this isn't about her. This is me not knowing how to be rational. I've broken her trust in the past, so she has no reason to confide in me. I broke her  trust in telling my best friend (her nemesis) about her family situation. I did so because I was paranoid. I need to be rational in the heat of the moment.

This is all word vomit. I apologize.

Provide a brief overview of the text.
<bot>: I'm clingy and I hate it. She may also be wrong, but I'm too infatuated to tell.
