We've been friends with another couple for 30 years, I'll call them Tim and Sarah. We're not as close as we used to be and now only see them about twice per year and message each other every couple of months. At the time we met they had just suffered the stillbirth of their second child and I was pregnant with our first. Obviously their loss was a tragedy and not something any parent ever gets over. Out of respect we were very careful not to push much baby talk onto them and kept our excitement to ourselves. Things seemed ok for a while.
Some years later I was pregnant with our 2nd and, knowing what a sensitive subject this was for them, we only told them when we had no choice as it was obvious. Sarah took it very badly - she actually ran from the room (they had decided against another child) and struggled to acknowledge we were having another. Seeing me pregnant was also something she couldn't handle.
Things improved with them after our second was born, and life went on. Many years later their first child, now an adult, had a very strained relationship with them and has been no contact on and off for about 7 years. In that time he has married (they were not invited to the wedding) and become a parent himself, so our friends are grandparents but have only seen the child twice despite living close by. This breaks Sarah's heart and makes Tim very angry. When we meet them we know not to discuss their son (the subject is always shut down) and rarely discuss our DC, which can be difficult as our children are a huge part of our lives. It's a bit of a minefield TBH.
So to today. Our eldest is pregnant and we're to be grandparents for the first time. I decided to message Sarah last week as I know they're seeing other friends soon who already know our news. I included the news in a long series of messages about all sorts, so it wasn't the sole subject of the text. She saw the messages straight away but there has been radio silence since although she's online every day. Knowing them as I do, this will be very hard news for them to hear.
My DH thinks it's ridiculous that we have to walk on eggshells around them and he's annoyed that they haven't replied to my last message. They've known our DD all her life so I would hope they're pleased for her. I do wonder if there's much point continuing this friendship when there are so many subjects we have to avoid - things that are central to our lives. Perhaps they would actually prefer it if we lost touch? I just don't know. It's sad to lose old friends but I can't see how this situation is ever going to improve. If I call Sarah I know she'll insist she's absolutely fine about everything, she always does, but she's obviously not. Would it be unreasonable to leave it now and accept our friendship is pretty much over, or should we continue with this strange situation where every conversation is a mine field?
