Top marks to you Rose for being so approachable. It sounds to me like you don't need too much advice from us, having handled the news well, just keep the lines of communication open and forget about your witness family. They have no right to know.
As a caveat to EF's advice I'd be careful about telling him everything you feel (i.e. the JW programmed thoughts) because once something's said, it's hard to take it back. My own mother told me that she'd rather I was dead than gay, before she found out I was. To her credit, despite being a JW she regrets saying it now.
Good luck!
