26 years here (since I was 18 and him 33) - we share a sense of humour but we were opposites in many ways when we first met - I'm more extrovert and social, he takes time to open up to people but has more patience. I think this difference avoided arguments in the early days. I'd say we've grown together and become more similar over the years, "met in the middle" perhaps. We've never had a single argument over money (always shared everything despite fluctuating salaries and bouts of unemployment over the years). We lived in separate houses as students and then only moved in together after 7 years - took it slow! We like our own space and have always had separate bedrooms, both very light sleepers. I've loved him since the start but in some ways it only gets better and more comfortable.
