Hi, sorry if I am a bit late with this one.
You don;t need to be married to be committed. My partner & I have been together 18 years - I love him, he loves me, we are together because we want to be, not because of some impersonal vow written by someone else. I feel secure because we trust each other & we share the same hopes & dreams. We are committed, and I don't beleive standing up in front of our friends & telling them that could possible make what we have any better.
I have heard said that marriage is what couples discuss when they have run out of other things to talk about!!!
Having said all that - each to their own - we must all do what makes us happy, and if you feel the need to be married then go for it - but why must you then send me a wedding list so I can upgrade your perfectly adequate belongings!!
