I know too well how that feels. I've got plenty of experience with that situation. Just remember that you're worth more than being just a background friend. I've gotten through it and gotten better friends, better confidence. You can too.

Mood But my friends don't know they like each other IDK if one doesnt like the other anymore or not lol but we still are together and we definitely make sure we have the same care and support for each other But don't worry, maybe it will be over soon, and if not maybe it's best to confront them about it
