DP and I have been together 8 years, living together for nearly 5. Lots of ups and downs but have come through it all and I would say we have a very supportive, loving relationship. No DCs and that's most likely the way it will stay.
I've always been staunchly anti-marriage but in the last year or so, I've been feeling that I would like to make our relationship 'official', or take it to 'the next level' or something
I'm not quite sure exactly what I'm looking for. I would not be a Mrs, I would not take his name, I would not wear an engagement ring (already wear a silver ring that he gave me as a gift) so nothing would really change outwardly but I find myself getting extremely excited about planning a wedding day (not a huge production at all, a quiet cheap-ish day but just a celebration of our relationship).
I support the Equal Love campaign who have launched a legal bid in the ECHR to extend civil partnerships to hetero couples, and if/when this judgement is passed (probably next year), I would absolutely jump at the chance to have a CP. So would DP, we have discussed this issue and he is up for either married, or CP, or stay as we are. So it's not the commitment issue at all, it's the 'married' part that bugs me.
I would love to hear other people's thoughts, whether you got married or decided not to, just to give me some extra food for thought 
TIA
