I personally want to do vows again as we didn’t write our own for our wedding, the celebrant just said what he thought was appropriate at the time.
Also, we’ve been through a lot in our marriage I think it would show a new sign of love and respect to go through with it. Hubby isn’t so keen but will work towards if in years to come like you said. Maybe on a milestone.
I hope you go through with it. It doesn’t have to be a grand elope. You could just book a night of baby sifting, go stay in the city and book the registry office and write your own special vows to share with each other and then have a special night at a hotel together to celebrate!
