My mother demanded a "one to one" meeting with my ex, when I was 6 months pregnant to "see where his intentions lay". Now... I was 28 at this point, already had an 8 year old, had been with ex since we were 14 (having known him since we were 11). I also hadn't lived with her since I was 18. I had a career, I had my own place, I was never going to get married (my parents marriage put me off, for life, quite frankly).
Why did my mother demand the meeting with my ex? Whom she'd known for half our lives at that point, near-enough? Because I'd had the audacity to have lunch with his mother two weeks earlier.
During this meeting, which I refused to attend, she accused my ex of "being nasty", "making" her light up a cigarette (he said: "it's your choice, but you'd better not do that around Contrary and the children!"), and demanded that he refund her for the pram she'd bought as a gift for my youngest.
My ex left there, came home, looked me dead in the eye and said "NOW I get it!". Until that night, I don't think he actually did, because I shielded him from an awful lot of it. Ironically? 4 years later, when he cheated on me and I kicked him into touch, my mother was the one wailing and gnashing her teeth...
Yet she still can't understand why I won't tell her if I'm dating/involved with anyone.
She also admits to hating my 14 year old, whilst going out of her way to enable my 23 year old (who is a chip off of my mother's block!). She (my mother) keeps bleating about how my daughter "never had a father" (erm... she kind of did and still does) and how my son "ruined" any possibility of my daughter ever being happy (he really didn't). It's beyond frustrating to try and make someone understand that biology doesn't equate family.
When I was newly pregnant with my son, at 9 weeks, I miscarried his twin. Hugely traumatic. My mother's response? On the day that I had the viability scan to determine if it had been a full miscarriage? Was to tell me, in front of my daughter, that I "deserved" to lose my baby because I was an awful baby growing up... and then she got snitty when I pointed out that she wouldn't know as she wasn't really the one who raised me. My grandparents and oldest brother did that.
