My best friend had a miscarriage while I'm pregnant.

While my hubby and I were TTC my best friend and her hubby unexpectedly found out they were pregnant.  Naturally there were tears of joy and excitement.  Then about 4 weeks later, on the day I found out I was pregnant, my BF told me that she thought she was having a miscarriage.  I reassured her that everything was ok and that bleeding was normal in the first trimester and to wait to see what the doctor said the next Tuesday.  The next day, out of complete excitement and joy, my hubby and I told her our news.  They were happy and said not to worry about them.  She even suggested I announce it to our other friends that we were meeting later that day.  Anyway, she ended up having a miscarriage. She never really talked about it.  I asked her how I could help and she says she's ok.  But things between us have never been the same.  She wanted to TTC again but her husband didn't.  Now I'm in my 3rd trimester and she's just watching all my excitement.  I can't help but to feel bad.  How do you help your best friend who's had a miscarriage?  How do you become close to them again?  I don't know how she's feeling, but I can empathize.  Please, any advice would be much appreciated!
