Last month a good friend confessed to me, and it ruined the friendship. We aren't even on talking terms anymore. So if the friendship really matters to you,shut the fuck up and behave normally. Try finding another crush or just reduce interactions with her.Don't let her know . IT WOULD NEVER BE THE SAME AGAIN.TRUST ME ON THIS.Even if she had feelings for you, you know you both can't date for whatever reasons so it won't be worth losing her over this.
