Have you tried talking with your friend about this? It may be that you will find out what is up if you ask her.
I have a few close friends and very supportive family members. I am lucky that I do not have anything to complain about with their reactions. I try to temper all of my 'reports' on DD with humour and then deflect quickly to ask about their DKs. If I want to talk about a particular accomplishment, I sandwich it in between asking about their family and a funny story about mine. People always want to talk about themselves and their families... it is a fact of life. You never go wrong asking lots of questions and being a good listener. Saying that though, it also has to go both ways. If your friend is not providing that to your relationship, speak up!
