That they may loose who they are, or already lost that or that your marriage will never quite be the same?! I’m freaking out!!

Me and hubby have such a good relationship and we have date nights and we have a 7 year old but she’s at a sociable age where we all go for days out etc and it’s nice and we don’t worry about late nights etc, we’ve got more and a social life now she’s a bit older with my parents baby sitting. but we know all that will change soon I am scared I’ll loose my identity..the romance and spark in our marriage :-(
