IF XH had had to ask my father before marrying me, I'd still be waiting tbh. Supposing he had ever got round to it, I'm not at all sure the old ratbag would have said yes, either. (Disclaimer: "the old ratbag" is meant affectionately, and my sister and I sometimes called him it to his face, although he did have his little ways.)
What happened is that I informed my father that XH and I were getting married and asked whether he agreed that my late mother would have liked me to use her wedding ring. He said ok then, and yes, I think she would, so I did.
I did also ask my dad to escort me down the aisle in the old-fashioned style, but the only options he had were to play his part with a good grace or feck off out of it, so I don't think he really felt he was handing his precious possession into another man's care, as it were. More like chucking the hot potato into someone else's unwary paw.
On a less warm and fuzzy note, I fail to see what the hell is particularly Christian about promising to obey the one with the dangly bit. Good thing I never agreed to obey XH, anyway, as he is an idiot.
