Have you ever?

I need some help.
Have you ever had that feeling, where you are totally in love with someone. Head over heels, all you think/talk/write about love.
But then one day, you're talking to them.
And there's just something that they do, or say,
and it's not even anything offensive or cruel,
it's just something they did, that almost totally dropped your feelings for them, and it's suddenly becomes that everything is awkward between you two?

I dont know what to do...

Yeah.
I can relate.
Thanks for making it feel like I'm not the only one, haha.
