I need help with a girl problem?

What a total shame for you to have her act in such a manner as she did twds. you. It was NOT your fault! So PLEASE KNOW that! Don't beat yourself over it, how were you to know, you sure aren't a mind reader!!! ALL you did was simply put your arm around her, not another thing else. I feel SHE IS the one who is NOT acting fairly twds. you! When you can see her & talk to her face to face, advise her you didn't mean to hurt her feelings, you're NOT that kind of person & she also should know that. Ask her IF she'd at least be willing to be friends with you, if not it's her call on what she wants to do. I feel she's making a LOT over absolutely nothing that's NOT your fault. IF she chooses to go her own way, DO NOT let it bother you as she's the one who's making something over nothing! Good luck, & do NOT worry about it, seriously!^
