<human>: We've been friends for about 3 years or so now, and I'm starting to realise this is very one sided. 

What started out as mutual friendship turned to her always seeking my attention (I've since learned she does this to almost all guys to get them to want her, then ditches them, probably a self worth thing) I told her I just want to be friends as I was pursuing a different girl at the time.

We hang out a couple times a week, 80% of the time instigated by me. The other 20% I feel is just her having no one else to hang around with. Furthermore, if we drink at her house or at someone else's in a relaxed setting, she often asks for some of my alchohol. I give in, because I don't mind sharing, but it's very one way in that she has never ever shared or offer end anything back.

I'm her "the person I call at 3AM when I'm upset" person, and similarly I have told her many of my personal issues to her but they're often brushed off after a minute or two of conversation.

It feels one sided. Should I say "hey, this is a kinda one sided friendship here" or just stop bothering? I like her, she's fun to be around but I think she just wants to be chased to feel popular/valuable, so should I just not bother?

Any reply is appreciated:)

Can you condense the text into a few key points?
<bot>: my friend is always the centre of conversation/situations, it's a one sided kinda friendship. Do I bother telling her I feel that way or just accept that's how she is and stop bothering?
