I agree that the term is over used. The people I'm thinking of are two who've lost their spouses.
One is a guy who's wife passed away from alcoholism, and it's been at least ten years. Each year on her birthday, he had a big drink session with all their old friends etc, but also with his new partner having to attend. Now I understand people have a past, but this new partner is a friend and I know it hurts her to feel like a booby prize by being at these 'birthday parties' where not only does she not drink, but she gets lots of really inappropriate comments from the drunken people there paying 'tribute' to the wife who passed away, and she finds it heartbreaking.
My MIL is doing something similar, my husband suffered from anxiety terribly for years, and turned to heavy drinking himself. He's been dry now for a long time, but his mother has been the catalyst for his mental health issues as she's always treated him like an accessory to her life, too many examples to list but she followed him throughout school (took a job in each school he was in), her adult kids are now all in their 40s but she will literally scream if they don't want to do Christmas/ Birthdays/ Easter/Bonfire night etc etc her way and no other way. Even when my FIL was passing away, his kids asked to have an hour with him but were refused, she has one daughter who married exactly as mum wanted, and one who called it off as she in her own words got so dragged down by bullying she couldn't have anything the way she wanted it.
When I married my OH, she had tantrum after tantrum and was horrible about every thing because as we were in our 40s and adults we chose things ourselves. So for example, I designed my own wedding dress and she told me I mustn't make it myself (I've done dressmaking for years) as maybe I couldn't keep a wedding dress clean and white (I didn't wear white, it was just another dig).
She refused to help with the food, we did our own catering, but then demanded I give one of the dishes to her so she could bring it as she didn't want her friends to think we'd done it all so I had to let her, and then she lost the spoon (I didn't care, all small stuff to me) but she told my FIL to look for a similar one on the wedding day morning while I was getting ready plus sorting the flowers/food/ venue issues etc - my OH wasn't here, he had to go to her house for photos to make it look traditional as if he was leaving her home to get married, despite having lived away from there since the age of 15.
She sat where my daughter was supposed to with my grandson to bring the rings, complained that she didn't have assisted seating for her and her sister who's in a wheelchair (nobody was having allocated seating) so I did set them a table near the toilets where she'd asked for it, when I got to the reception she was sat in the corner table in front of the nibbles, so nobody could get to them so she could plug in her beer pump, we had provided mocktails due to having a non alcohol wedding.
Then after she'd refused to help at all, mocked the dress, my bouquet, told me my OH wouldn't love me as he would eternally be in love with his school gf, recoiled from my best friend as he's Indian, and so much more she got her grandson to stand up at the wedding and announce she'd done it all so she could have a round of fake applause.
The finale was she'd been asked to lock up after we left the reception but she got drunk and just didn't, so we got calls into the night until one of my friends sorted it. We had to have the venue near her house, but then she booked a hotel so she still could enjoy the 'wedding night' - she insisted we drop some of our guests so her friends could come, she snatched the car park keys from my husband at the reception to let her friends park even though we'd told her that parking was needed for the DJ/ band/catering van.
We donated the left over food to the homeless, apart from some cakes her neighbours had entered into our cake competition (she came over early the next morning so we had to dash from our wedding night hotel to get them for her to take back).
Most hurtful of all, when FIL passed away, my husband was still struggling with heavy drinking - she knew this but insisted they both go and buy fast cars with the inheritance - hubby told her he was feeling very low, and not managing well and had felt suicidal (it was during covid, and he had lost his job) and said he would rather use the money for therapy. She also mocks therapy so got angry and then refused to see him for almost a year, she would text abuse and nastiness and even though he begged as he just lost his dad and didn't want to lose his mum she said he didn't love her or he'd do what she wanted! I decided to tell her I wouldn't speak to her while she was being abusive, so she tried to call me (while refusing to take calls from hubby) and I left it at that.
This went on over 2 years, at New Year I sent her a text saying I would like us all to move on positively - she still didn't reply and is still being nasty to hubby, even though he's had his therapy, stopped drinking etc and is still getting nasty comments, always put downs, nasty remarks and manipulative behaviour.
He told her to process his dad's passing out would help to have a place where his ashes are scattered - she's said no. Then he said he would like to do a memorial plaque - that also got a no, and with it another guilt trip that he should wait until she passes and be thinking about her plaque, and his dad can be added to it.
Now she's having an 'event' to mark FIL passing, on Easter Sunday! She's hired a hall, it's a booze up, everyone she knows it expected to go and give up their weekend easter plans.
It might sound like it's just me being sour, but in fact everyone (hubby, one sister, all in laws, friends of the family etc) all say they don't like being around her due to how nasty she is to and about everyone, she gossips, she's racist, she drinks and gets mean, she gets so hysterical the adults and kids get uncomfortable and can't even eat, sleep, enjoy anything where she is. Yet they're all scared of 'upsetting' her even though she's permanently in a state of mean.
This is another example though of her trying to get people to do what she wants, she's already said anyone not coming to this party are disrespectful of FIL birthday. But he passed away 2 years ago and was a gentleman who always thought of others, I think he'd be mortified by this - I have Easter plans and she doesn't talk to me anymore (thank goodness) , but others are giving in while upsetting partners/ family etc and I'm being told I'm 'lucky' as I don't 'have' to be involved anymore. I see this as another example of narcissistic control, using grief to get others to do things they funny want, like my friend and her partners birthday parties for his ex?
