My lb is 12 months old. Me and my partner are not married and we gave our son his surname.
Over the last 12 months we have been getting on less and less to the point where I think I'm going to have to finish the relationship because I no longer want to be with him (we argue on a daily basis).
Would I be unreasonable to change our sons name to double barrelled whilst we are still together to ensure he agrees to it so then it's done for when I finish things?
