My FH's daughter is one of my bridesmaids in which he has joint custody of. She is a teenager and when she gets mad she will just stop talking to him and coming over. The problem is we are needing to go pick out dresses and at this moment she isn't talking to him. She doesn't have a good reason not to talk to him just if she doesn't get something she wants or get her way she will just stop. I can't keep putting it off and what if she decides at the last min to not even come to the wedding. I would love nothing more then for her to be in the wedding but at this point I don't know what to do. Any suggestions would be helpful.
