"She will do as she wishes-but yes if she marries i will force myself to attend and smile. And fucking sob from her being engaged forward every single day at what she will be losing"
So if she enters on a marriage where she will be treated as an equal, contributing equally and getting an equal amount back, living in a friendly, sociable, mutually supportive relationship- you will sob?
That sounds exactly like dh's grandmother. There was nothing wrong with FIL, but her experience was negative, so it had to be negative. And though tbf she didn't sob openly after that the wedding, they all knew. It cast a bit of a pall over family reunions. And her dd never forgave her for being unable to see beyond her own prejudices.
Oh and if you claim the above relationship couldn't possibly happen- that was my own marriage I was describing. Dh and I have been together 35 years, we both work, we both contribute equally to the housework, he has never pressured me into sex, not once in 35 years, and he is the best companion I could possibly have.
Am fully aware that my own dd may or may not end up living with a man or with a woman or on her own, and I would be fine with any of those as long as they are right for the person she is, not for the one I am.
