haha relax, i'm not making a 'big decision', i'm just saying that IF i met the right person at 18, i would marry them. no i haven't done 'research' because i know this isn't ACTUALLY going to happen.
yes weddings cost money, i didn't say anything about a wedding. not everyone wants to invite ten thousand people to watch - some people just want a private ceremony. i don't think weddings really mean anything, it's just a celebration of the marriage (ie the marriage is the important part).
and financially, i already pointed out that a lot of young people live with other young people when they're going through uni or whatever - what's the difference?
