Uh, it's a tradition in English society that the wife takes charge of the wedding plans, and I think also that her father foots the bill at least in part. Whether or not any of that holds true for these circumstances, it's generally accepted that most men would be equally happy with the registry office and aren't particularly up for partly or wholly funding a gigantic fairytale wedding which means bad speeches, overpriced food and in-laws they don't like. This is because wives dream of weddings and husbands don't. So naturally, this being very important to the wife and less so to the husband, it's more about the wife than the husband. To pair stereotype with stereotype, the OP's fiancée is possibly equally bemused at the thought of spending more money on the computer, which is after all just a box of electronics. Oh, piss off. You've never met either of them, you aren't getting married to her and all you know about their relationship is that she wants a new dress. That's hardly indicative of the fact that the OP is some sort of doormat who gives in without a fight; indeed, he came on here asking whether it was unreasonable of him to kick up a fuss, not whether it was reasonable for him to lie down and take it. The wedding, as many, many people have already pointed out, is very much in the wife's domain. I expect that other things will be conversely very much in OP's sphere of influence; that may not suit your egalitarian ideals but since you aren't in the relationship in question I wouldn't idly suggest that he knows nothing about equality and partnership. Also, OP is committing himself to a shared lifetime. Sometimes he has to know when to give and when to stand his ground. Given that the wedding is something his wife-to-be has probably been formulating since she was old enough to play Mummies and Daddies he's got good reason to let her have her way just this once. It's not exactly the slippery slope to financial ruination. The truth, this is. Average wedding cost in the UK exceeds £20k, which is as far as I can ascertain the security for a medium-sized mortgage. Given that you're blowing the money essentially on paying for people you may not like very much to have a good night out, I don't personally see the point. Imagine how good a honeymoon £20k would get you following a £50 registry office marriage.
