<human>: Can you provide a brief rundown of the text in within 3 sentences?

So Ive got this really good friend who Ive been friends with for the past 4 years or so. She is probably my best girl friend. I am somewhat interested in her but always kept her on the back burner because I always figured I'd get the "we're just too good friends" shenanigan. 

So she is very flirty with me, always calling me hubby and that Im her favorite and all that. We used to text every day, but now we dont text too often, which is usually a clear sign that she's not too interested in me. Cool, no big deal.

But she CONSTANTLY flirts with me and gets my hopes up. When Im with her in person, she is very talkative and I always get the vibe that she is interested in me. And because I am somewhat interested in her, every time she flirts and I try to make moves only to them come to no avail or not be returned, it bums me out and pisses me off. In one instance she did it so badly that I got so mad I didnt talk to her for a while, which she got upset about and kept pressing me what was wrong.
<bot>: how do I handle a really flirty best friend who Im kind of interested in but when push comes to shove, nothing happens.
