Today I Sung At A Wedding

As the title says, I did sing at a wedding today, with the school choir. It was the wedding of 'Handy' as their combined name is lol. Now, I am quite the sceptic when it comes to marriage and seeing as my friends are convinced that I will definately marry now that I have said that I do not want to, I decided that it'll be good to note down some of my views on it and see what I think in years from now.
My thoughts on marriage:
1. I take it very seriously, as a Catholic I believe that it is a sacrament, and as it is in the Bible, a time in which the man and woman become 1 person in Christ's eyes and therefore can't divorce. Now I as I never want to divorce, I'm less likely to if I don't marry at all.
2. If humans always make mistakes, how are they supposed to know who is 'the one' for them? Because if you can't divorce you therefore cannot technically be forgiven like in confession and then have a clean slate afterwards. I don't understand how a person can tell, I mean it's not like they get visions from God telling them, that it is 'the one'.
3. You are stuck with this person, even if you both have gotten over the fact that you may have different views on some things, once you're married you'll probably find it alot harder to getting to a mutual agreement.
4. People change over time. That's just life, who's to say that in 10 years time you'll still both get along when you perhaps become influenced by different things and therefore changes your personality, e.g. Am I still the same person I was 5 years ago?... No. And because you've promised to stay by them no matter what, you have to try and put up with the person, even if you can't stand them anymore because you promised God. Marriage is supposed to complete you and make you happier, but in the long run... will it?
5. I'm not keen on having kids. Well, I'm not, as I want to become Mayor of London... there's not much time for children in my shedule. And you know that the husband would at some point get a bit vexed about it... even though they aren't the ones going to hell and back through pregnancy... and then there's the actual labour...
6. Apparently, everyone changes when they are married... it might be for the better... or the worse.
7. There are too many variables to make things go wrong- why risk it?
8. If they really love you then why can't they respect your wishes? If they do then maybe they are 'the one' and then you do end up marrying them anyway.
