Dh and I have been friends with a couple for a very long time, about 20 years.
We both have 2 dc - our kids are similar ages and were very close growing up as we live near each other. We've been on holidays together, and shared countless school runs. She and her husband are such a lovely couple - they've been together since uni, and he is so supportive of everything she has ever done, delaying his career and raising the kids so that she could achieve her goals.
My friend has had mental health problems in the past - periods of depression that she has been on medication for. She has always been fine in the end. However, since her youngest left for uni last September, she has been really down, and last week announced that she was leaving to go and stay with friends to 'get some space'.
I know it's her life, but aibu to worry that she's throwing her wonderful marriage away? Would you say something in this situation?
