My question involves criminal law for the state of: GA.

My husband and I took his children to his ex-wife's home today after our christmas visitation and were told that I was not to accompany him anymore to her home, even though we just get out of the car and kiss children and leave. Since our marriage last year this woman has made it very clear she despises me. Her children love me and she can't stand it. She is a manipulator and a control freak and she basically just wants to tell us what to do. She said if I came to her home anymore she would call the law and have me arrested for tresspassing. Keep in mind, nothing has ever happened to warrant this behavior from her. There is a sidewalk around her whole neighborhood, my question is, can she get me for trespassing if I am on the sidewalk? Thank you for your help!
