Tired and ConfusedšŸ™ƒ

Hi girls!! Iā€™m 14 and Iā€™m having a lot of trouble with my sexuality. When I was younger I had a ā€œgirlfriendā€ even-though we were in the second gradešŸ¤¦šŸ»ā€ā™€ļø Recently though itā€™s came up again and I really donā€™t know if Iā€™m bisexual or not. How did you guys know when yā€™all were? Thank you in advance!!
