My Uncle married a woman almost 20 years younger than him many years ago. He had two daughters by his first wife and his second wife (who I'll call Aunt as he met her shortly after I was born) had no children at all before him or with him.
She's always made out that she never wanted children, that children take freedom away, that she was too career driven etc. My two cousins (uncles daughters) both tried to have children of their own but both struggled with fertility and so never had them either. Both are wonderful with my kids when we see them. My aunt makes me feel inferior for having the children. She'll say things like "I always thought you'd be a lawyer. It surprised me when you had the children quite young..."
My Aunt is a very attractive, intelligent and classy woman who has always been aloof and quite self centred at times. She once likened herself to Princess Diana. More recently she has begun making odd comments. Often on socia media too if I post something of the children. She has never ever once said it was my choice to have children like it or lump it, but you certainly get that vibe from her. She makes abrupt remarks and if I mention that a child has vomited, she turns her nose up and says how disgusting it is for me to mention child vomit, yet talks openly about her dogs stitches coming open and about her recent eye operation in detail.
Do you think that actually she regrets having children and that's why she makes all these condescending remarks and pulls all these ridiculous faces? She's made a flippant remark today about me trying to get a GP referral for my child as I think she potentially has a food allergy/intolerance.
Other family members laugh about it and clearly think she's something special. Personally, I think she's quite sad about her life.
