I am actually wearing the dress I wore on our very first date, hes always told me how much he loved it, I'm even getting my makeup done professionally beforehand.
Oh hunny, I'm very, very worried you're setting yourself up for an emotional landmine here. I'm just not sure what's going to blow you to smithereens yet.
Be very careful here. Tread lightly. Don't lay it on too thick for him. He will want to run if he feels you chasing him. If you plan to keep the professional make-up I strongly suggest you take May's advice and pick something else to wear. Something that is your favorite not his.
I'm worried you're setting both of you up for failure here. Please, please try to take your expectations down like 87 pegs because I know you aren't in a place to immediately remove expectations from these situations yet. If you must go in with expectations please drop them to the floor.
