You won't likely get jail for the first time but be very very cautions. The Order bars you from contacting her. It's really not a mutual order even though she should be treating it as such. Don't even begin to think the law won't enforce it just because she contacts you. Be very careful because I believe 3 or more infractions is a felony.
Our office handles these kinds of issues on a regular basis. It is even possible to request a hearing to quash the Order of Protection she has against you. If this is something we can help you with and you are interested in hiring an attorney, please call us.
You asked if you can get jail time - without reviewing the police report and knowing your prior criminal history, if any, we can't say for certain. But it is unlikely if there was no violence and no prior criminal history.
