AM I BISEXUAL

I have an issue I am 14 and sexually confused I like guys and I don’t want to like girls but my best friend makes me feel things when I’m with her like I feel weird and I try hard not to but I can’t stop feelings sad when she isn’t around we ride horses together and she is over almost every weekend I am so confused and I don’t want to lose her but I also don’t want to be sexually attracted to her. I have never felt the need to touch her in any way sexually but I have felt the need to hug her and make her happy .I talked to my mom about it she said it’s normal to have a girl crush on your best fiend but it creeps me out PLEASE LEAVE ME SOME ADVICE ON WHAT TO DO OR TELL ME IF I AM OVERREACTING
