How to help my fiancé deal with his mother's recent relapse?

My mother was just told today that her bc has come back too, she's had BC 2 other times.  I'm also getting married in 3 months.  This is my first time on the message board and from the looks of it I'm sure you'll receive a lot of good advice.

I know each person is different the way that I found helps your loved one work through this difficult time is to talk to them the same as you did before the diagnosis.  I talk to my mother and get updates on how she's doing but the part of the conversations where I can take her mind of things is the best.  Keep a positive attitude, be there for them both, let them know you're there for them.

Prayers are with you and your family.

I think Dottie covered it well - take your cues from your fiance and let your fiance know you are there and will do what ever is necessary to make it less difficult.
