This is a long story - I will try to condense it. I am looking to vent and get advice (AIBU doesn't really fit, but couldn't find a better category).
My sister-in-law had several early pregnancy losses. We were so sad for her. We sent her flowers, would always ask how she is feeling and getting on. She is didn't really ever discuss with us, which is understandable. It might be worth mentioning she is on the autistic spectrum. I can't quite imagine how awful these losses must have been, as you must be grieving the life, hope and joy you thought you were going to have.
We used to be friends with BIL/SIL - go out for meals, cinema, boardgames nights, etc. Then got pregnant. We messaged BIL/SIL first, to express their might be mixed feelings, but I am pregnant. The invites then stopped...
At social events, my SIL would not say hello, not look at me, when she saw me she would turn and walk the other way. When sitting at dinner tables, she would spend the whole time looking at the ceiling or opposite direction to me. During my pregnancy, my in-laws would start talking about 'being a nanny for the first time...' etc. then immediately cut their sentence off, with worried expressions, as they realised SIL could hear. It was like the family couldn't feel joy for us.
I had a friend who was going through IVF at the time. My SILs reaction to my pregnancy made me feel so terrified to tell my friend I was expecting - as I thought maybe react the same. I felt really alone and had no other friends with babies. I remember crying at a midwife appointment about it.
All of the above continued after having my lovely now two-year-old. No acknowledgement of her, no talking to her, etc.
As of the end of January 2026, BIL/SIL have welcomed a baby girl into the world. I am so glad that they have had their baby. But I also feel resentment - that they could have their pregnancy, the family were allowed to feel and express full joy, that they are now allowed to discuss their birth openly, have full support, etc. I just feel resentment that we weren't allowed to have this, and that my BIL wasn't there for his brother after a horrendously traumatic birth.
I can definitely get over all of the above, so long as SIL/BIL do actually start talking to us again at family events, looking at us, acknowledging my daughter, etc. I know we will never be such close friends again now, but I just hope they can act normal with us. I don't want to feel these feelings when my MIL is talking to me about SIL. I just want to get over it!
Has anyone had any similar experiences, or have any advice?
