I felt up a girl was 14 she felt bad about the ?

whole thing after. she told me to stop calling her when i asked her if what she was felling was bad she said yea my question is when she sees me in school when we go back and she is going to have that same feeling. can she get me into trouble with the school meaning will she tell on me. i only felt her up and toched her thats it. do i have somthing to worry about when i go back to school or am i just over reacting
