CNY 2019

my divorce is still pending . I have 3 yr old daughter. My husband lives with Mistress. My in-law once every 1mth/2mth come and vist my daughter. I want to ask is it necessary/must to go Reunion dinner?? The whole 2-3days visiting?? honestly i seriouly dont wish to go. My only concern and stressing me is. What if i dont go, i scared my husbsnd dispute and wants to contest the Divorce. Now is uncontested wer both agreed. How How How. I am in a freaking dilema and stressed up.
