<human>: Like seriously man. It's so annoying. When I do initiate the conversation we always end up talking for a few hours, and often it just goes on until one of us goes to sleep. So it's not as if she seems completely uninterested. There was one point where I messaged her every other day for a couple of weeks, but then I realised that I was the only one actually initiating it at all. The only time she ever, ever initiated anything was her messaging me to say happy birthday, but that wasn't even a full blown conversation. I started thinking to myself that maybe I'm annoying her and she's just replying out of politeness, or that she's not interested. I decided I wouldn't message her first this time, and I thought if she's interested in wanting to talk to me she'd hit me up after a few days. It's been just over a week now and nothing, apart from liking one of my Instagram pictures. I really want to message her and talk to her again, but part of me thinks if she doesn't even value talking to me enough to start the conversation just one time, then why should I try so hard? I just feel like I'm being desperate and clingy. I know people always say guys should be the one to make the move and whatever else, and I know she is a shy person, but come on. Even one message from her would show me she likes talking to me and that I'm not wasting my time, but nothing. I don't know whether to give up and assume she's uninterested or keep trying and potentially waste my time and hers. It's so annoying not knowing where I stand man. Part of me wants to quit, but I really, really like her, she's a great girl, I just wish I had a better grasp on what she thinks about it all.

Can you summarize the given text in a few sentences?
<bot>: Messaging the girl I like quite a lot, but I start the conversation every single time. When we do talk it goes on for hours though. Is she interested at all, or am I wasting my time?
