I got married 20 years ago because I wanted to have a secure family to bring children into and I knew it would make my elderly parents happy to see me 'settled'. I also naively thought it would guarantee fidelity...
ExH obviously didn't think the same and I got divorced 4 years ago. I'm in a happy relationship with DP now but we have no intention of getting married as we can't see the point.
It's made me think though - why did / would you get married second (or subsequent) time round? I'm not criticising anyone who does, just interested to know why and what difference it made, if any?
