That is the usual way it goes. They (those in charge of diocese) are scared to death of the law suits and find it easier to abandon those who they may even believe are innocent. There is only one organization which helps priests that I know of in this situation, it is called Opus Bono Sacerdotii. I hope Fr. Robinson has been in contact with them.
To me he doesn't seem to be the assertive type. But former parishioners love and support him.
