I wish I could give you more help this this, but its all I got.
Be kind to the girlfriends and fiance's that may call/email you. We know that we are not allowed the same rights as well as the wives and husbands are, but we care just as much.
XH was overseas while we were dating and the FRG at that time was SUPER sweet to me and another military girlfriend that I meet on base.
We didn't get as much information, but we were never left totally in the dark either. She was very respectful of us and didn't talk down to us or anything like that.
Without her, I would have never have known XH actual return date - and would have missed him walking in and the first hugs and all of that. It was so meaningful.
This was all 11 years ago, so things may have changed, but it mattered so much to me.
