I guess I have never really given any thought to how I feel about changing my name. I could live with or without it.
But my FSIL has the same name as I do. And I think she maybe insulted if I were to have the same last name as well. She already "feels like she is losing her brother", she isn't really a fan of sharing him. The confusion of us being together is normally resolved by going by last names but that won't work if I were to change my name. I haven't outright ask her what she thinks but I don't think she will be very happy about it.
Even if there wasn't this shared name issue I would still consider keeping my last name.
Thoughts?
