Haven't confessed but

anyone i crush on has always has mutual feelings as well. Once i find out it's mutual, I'd be super happy for a few days. After that, the feelings just evaporate. Like, i'm suddenly not into them anymore.
It sucks cause i'm such a romantic and i usually have had feelings for whoever i'm crushing on for a long time. For it to just go poof after knowing that it's reciprocal, really sucks!
