I’m getting married soon (It’s my third) and on my first marriage I changed my surname to be that of my husband’s (I was 19) but didn’t for the second. I’ve kept my first husband’s surname to this day as we have two DC and I like having the same surname as them. My fiancé wants to me change it to his own name as he feels like having my first DH’s surname is weird and as if I was with another man. He says the DC are adults now and that it shouldn’t matter about their surnames. But frankly I don’t want to change it as I’ve had it for 30 years now. This is causing friction between us. Am I being unreasonable here?
