What are the possible results of a restraining order hearing?

I am in the midst of a divorce. Unfortunately we still live under same roof. She has made several threats that she would make false allegations against me and call the police. Her boyfriend has also made the same comments to me. We have five children together and I don't want to take the chance that she could have me removed even temporarily. I bought a voice recorder and have been recording every minute I am in the house. Well four days ago she started yelling and cursing at me in front of the children. I went to my bedroom and locked the door and asked her to leave me alone. She began kicking the door and cursing at me with the kids present. I asked her to leave me alone and she started kicking and yelling more. I called the police. They arrested her and a judge gave me a temporary restraining order. The hearing is in a couple of days. I am nervous that the TRO could be dropped and she will be allowed back in the house. Anyone had experiences like this? What typically happens?
