I remarried at 29 and my friends threw a bachelorette party with the whole nine yards. No, no male stripper was nine yards, silly. We had loads of fun, but the stripper kind of got into the role a bit too much, which only made us laugh harder. So sad he didn't realize we were laughing at him. Nobody got raunchy or caught up in the excitement to do anything. We were drunk but not stupid.
If you've been together for seven years, which is a lot longer than we were, then you would know what kind of person she is. Is that why your worried?
Look, she will have fun but she's going home to be with her husband whom she loves so much she wouldn't think of spending her life with anyone else.
Congratulations and best of luck!
