My husband has 3 siblings. A few years ago their father (my father in law) had a terrible accident and almost died. One sibling still hasn't been back to see the family, even when his father died and his mother got cancer.
My sister in law hates me and has since she met me over 20 years ago. She's excluded me from family events, been nasty, made false allegations etc. She snubbed our child's christening and our wedding.
My mother in law has always sided with her daughter and even made allegations I've said things I know, and my husband know, I haven't.
For the 3 years preceeding my father in laws death, I always ended up being the most practical care giver when present probably due to my experience in healthcare. I even got palliative care for my father in law as he lay dying as they didn't want medical intervention and were in denial. I fed him. I got him water. I sat with him. When I explained why I called an ambulance to get him palliative care involved so they'd avoid a coronors inquest, a post mortem, him dying in pain and them being questioned for not getting him medical attention etc, my sister in law just stormed off in a huff. She never thanked me. She's never been kind to me.0
Now my mother in law is alone. She has a myriad of health issues. She requires lifts to hospital appointments and things doing around the house from time to time. Her mean daughter who lives 10 minutes away with adult children never answers the phone, is too busy, always has plans etc. The sibling abroad does nothing - still not been back even for his fathers funeral. The other sibling does what she can but lives 2 hours away and doesn't drive. She does come to stay with her mum for a few days when her mum has operations etc.
However, all this running around seems to land on me and my husband and we have young children. Also, I have my own widowed mother nearby. I only resent it because my sister in law and brother in law have always been nasty and rude. I'm at a stage when mowing lawns, dinner invites, driving to medical appointments etc is annoying because I'm not her daughter, it's not my responsibility and it's not thanked and it's expected. Why should my husband (who is a busy shift worker) use his annual leave to do things for her or me use my own time when I get nothing but sneers and abuse from his family. They enjoy their holidays, day trips, lots of money from working. I'm too busy running around after everyone else to even consider working. I am fortunate to be a housewife but we've obviously made sacrifices to do so. My child also has high functioning neurodiversity but needs routine so I'm delighted I can be around for them.
My Mother in law voiced that I am her responsibility and my children are her Grandchildren so that make her even more my responsibility. She thinks I owe her because her son married me. She says she is my responsibility. Whilst I agree in being a decent person, am I being unreasonable to resent doing things when 2 of her children are absolved from responsibility yet she makes excuses for their selfish behaviour and thinks they're wonderful. This makes me feel angry and I feel that despite her generosity financially many years ago when we married etc and to ALL her children, I am the only in law she feels owes her for some reason. Don't get me wrong, I am grateful, but I don't believe she is solely my responsibility. I am not her child. AIBU?
