All these things that I have done

OK, you are not interested in marriage for reasons mentioned in your entry. Fine, I respect that. However, never say never, this is one thing that I know. If you love someone so much, you may want to consider it, if only because you love the person and for making your vows public for the world to know. Also, it isn't true that co-habs lives are easier to manage in case of a break-up. It may end up worse because nothing will be backed by the law and it would be "who-gets-what" arguments, with long solicitors bills if it is really bad (it happened to my sis). Everyone would be a loser in that scenario, believe me, as it will end up being a much longer procedure, more money to pay, accommodation to sort out...Marriage may be more of a financial/administrative security, possibly with a contract at the start, for peace of mind. It isn't because I am divorced that it means "marriage" as an institution is a failure. If anything, it can be seen like a legal contract between partners. Some people may like it, some may not. It's up to people to judge this.
