Help, I have a memorial ( spreading ash's ) of a dear family friend Saterday DH  SS DIL & myself will be travelling together SD will be also attending, after only starting talking/ texting  DH (all her ) for only just over a week of no contact SD is asking if after the event does " he " want to have dinner with her & other family members I have told DH I won't do this if he would like to I will stay home and let him have family time but he doesn't want that & we compromised we will have a drink with people there then go sit by ourselves & have dinner. I know she will swan all over DH to try to show family she has her daddy back he wants me to be civil but I will not even acknowledge her & will remove myself from the event if I don't feel comfortable. How do I ignore her & not look like a bitch to everyone else actually I don't care what I look like they have pretty much all sided with her & she really couldn't say anything worse about me than she already has I just need to kept composed but I actually want to lash out at her & rip her bloody head off, wish me luck I'm gonna need it lol
