I need your stories...?

I'm writing a song about a failed relationship and how one person has this whole fantasy in their head of what's happening, but then reality sets in, and she realized they'll never be more than friends because he's gay...but basically i need heartache stories for inspiration, if you're looking for a place to vent about hard times this is the place. please help, even if you want to put down some words that speak to you, that works too:) thank you so much
