thanks everyone
yer think might just keep my name that way were all the same as dont want any of my kids to be different. also if i was to give lucy my partners surname my son who has just turned 5 may have some difficulties understanding. so if i keep my name and we do get maried itl be more special as the children will be gaining his name too.
