I've been with dp over 16 years, engaged for 7 of those, but I doubt we'll ever actually marry ( unless I wear him down 😁). He was my boyfriend then fiancée for a bit, now he's my husband ( partner sounds like we are same sex and we're not, so don't want anyone thinking we are!) After being together for so long it's just easier. I would even think about changing my surname to match his and our kids (as this is my main reason for wanting to marry these days). We moved continents together so I don't think it's the commitment thing that is the problem.
