Distraught

My fiancé has gone awoll... Yesterday I had to send him to the psychiatric ward because of unexplainable behavior he was doing. But now he is upset with me and won't talk to me every time I call to check on him he hangs up the line... And there is a possibility that I'm pregnant. I don't know what to do or if I should just give him space. But I'm getting myself worked up I have been crying ever since....
