I am marrying my fiance this spring and it will be a second marriage for both of us. The only hitch we've seem to come across is the name change. He has a 5 year old daughter and my son is 3. My fiance and I both get along well with his ex (she is not re-married yet, but she's been living with her boyfriend for over three years now.) However, my ex is now completely out of the picture for me and my son, but we both still have his last name. My concerns are 1. Is it not super weird for him, his ex wife, and I to all have the same last name??? and 2. I feel awful that My fiance, his daughter, and I would all have the same last name and my son would not, especially since my fiance has already stepped into the "dad" role. I may be overthinking this, but I'm afraid he will feel left out as he gets older. I want to have the same last name as my son, especially down the road when he goes to school and participates in sports. I'm very reluctant to change my last name again, but I know it would crush my fiance. It's something we have yet to agree on....
