Be honest with your partner about marriage doubts

I’m 27 and have been with my boyfriend for three years.

I love him and we have a good sex life, so though we’ve never been the kind of couple to rip each other’s clothes off, when he proposed last month, I accepted without hesitation. I am almost sure we are doing the right thing, but some part of me can’t help wondering whether he really is the one.

Have we got enough sexual chemistry to last us a lifetime? What if I marry him and then two years later fall in love with the man who I am really meant to be with?
