Getting along with ex's

Girl just make sure that you are the finest thing in there(next to the bride) and be cordial. You don't have to break your neck and kiss &^% or anything but if you happened to bump into each other give a "how you're doing? (daughter's name) looked beautiful.", and leave it at that. If she was a true WOMAN, she would put any hatred behind for the sake of her daughter. Just think, you won't have to see her anymore after that and honeslty at the end of the day it's not about you two it's about the daughter. Let her have her day.

Honestly..your best bet IMO is to just be there for the occasion..so what if the ex is there! You are NOT there to see her, for her, etc etc..you are there to show support and love to your stepdaughter! so do just that...If the ex tries to chat you up, be civil and pleasant..if she for whatever reason tries to stir up trouble....BE CIVIL AND PLEASANT and calmly let her know that "this is not the time nor the place, we're here for a joyous occasion so lets just enjoy it..whatever issues you have with me/my husband will still be around tomorrow/at a later date but I refuse to do this here, now" or something along those lines...and if she STILL tries to cause trouble, have your husband deal with it....

At our wedding, my MIL and Step-FIL had to get along with my FIL and Step-MIL. I don't think that they had ever been in the room altogether like that in 13 years! Everything went fine, everyone was nice to each other. I suggest you just say hello, the if she wants to chit chat with you, I am sure she will.
