When my sister was pregnant, I was told is very unlikely I will have kids. I was devastated. I reached out to her thinking she will understand as it was her second pregnancy. She instead offered me money to freeze eggs which 1. I did not ask for, 2. Probably wouldn’t have worked. It broke my heart, we ended up having a huge fight and she told me to not bother... I did not speak to her for almost a year, I did not congratulate her on the birth and refused to talk until she apologised. Instead of an apology, I received a very long text of excuses how she had morning sickness and was busy and couldn’t deal with me blah blah and she meant not bother her in the moment, but I stopped talking to her and said not nice things to others and it was all my fault and my reaction…. The not nice things I said to other was the above - what happened and 9 out of 10 people told me I am right to stop talking to her..
I did end up pregnant , I had terrible morning sickness, and absolutely no support from anyone, while working full-time. I still found time and energy for my friends who were separating, divorcing, going through struggles, etc. even when they had zero time for me and barely checked on me or my existence after I announced my pregnancy.. I have exchanged maybe 3-4 messages with my sister and we have absolutely no relationship.
I have been on both sides, and while neither of you approached the situation correctly - what my sister said to me in arguably the worst moment of my life is why I do not want a relationship with her anymore… she was not the only person I cut out at that time when I had enough..
While I can understand feeling stretched and out of capacity during pregnancy, it is absolutely no excuse to treat your sister like that when she is going through infertility. It is painful and it can be incredibly triggering to see sibling get easily something you wanted for your years. I wanted children since my mid 20s, my sister didn’t realise she wanted any until her late 30s and conceived with no issues in her 40s, whereas I was facing premature ovarian insufficiency
in my early 30s.. I was happy for her, but equally I couldn’t show up and be as happy and excited for her while I was grieving the life I always wanted and she had and didn’t appreciate…
