I was somewhat in love-ish with XH (and vice versa) - but I was not head over heels in love with him and neither was he. I did love him, though, still do, and he loves me.
There was a lot of pressure involved. Not, of course, to marry a virgin and produce an heir and a spare - we are both mere peasants, he and I. But there was the looming threat of him being made to leave the country and the prospect of him having to take over his family farm with a PhD in physics and precisely zero interest in agriculture.
We have been divorced for over a decade. Nobody feels happier and prouder that he has found the woman who wanted the same life he did and nobody could be more pleased at his three little girls than me. Nobody has supported me more in realising my professional ambitions than he has, and nobody except him refers to me as "Madam Director" because nobody except him gets how hard I have had to work for it, how much sacrifice has been involved, and nobody has been anywhere near as supportive!
"Whatever love means" you say - as though it is always somewhat 2nd rate. I think the notion of not being head over heels for someone gets a bad rep because of Charles.
I love XH, and XH loves me. We just were not meant to be as a couple. Ours was not and is not the type of love that is romantic or even just driven by lust. He suits his wife much better than me in that respect - and while I have not re-married there have been others before and after him that I suited better than him in that sense, too.
But he is and probably always will be the "platonic friendship" love of my life. Our only mistake was to assume that a heterosexual man and woman ought to have some sexual or romantic attraction. We really just do not gel in that way. But we do love one another deeply.
So, whatever love means, I suppose!
PS: not saying that Charles and Diana loved each other in that way - this is clearly different.
