Please please help me

Ok so today we had a field trip and our class took a picture. So I put my arm around the two guys beside me because that’s what I do in pictures! Anyway one of the guys was mimicking me and put his arm around me as a joke and I ran off because we were all running to the next spot (not immaturely). Anyway his girlfriend broke up with him for that and she is so mad at me. She plays softball with me and her mom knows my dad and I have a feeling her mom will tell my dad something that’s not true! Please help I’m freaking out and I don’t want to loose this friendship or anything! Please please help

UPDATE: she’s not mad! I’m so relived! I explained everything and she wasn’t even mad! Soooo happy! Thanks for all your help!
