Engagement Party Invitation
I have been dating a man for 2 years. He is divorced and his second wife, now divorced wife, is hosting an engagement party for their daughter. I have never met his ex-wife, but have met his daughter several times. Since I will be visiting him on the weekend of the party, his daughter invited me to the family enagement part to be held at her mother's home. He would like for me to attend with him but I suggested that I cancel my visit until a more convient weekend. He then wanted me to visit, but spend the evening alone while he goes to the engagement party without me. I think this is an important occasion for his dauthter, son-in-law and their families, and think that my presence in town would change his plans or the dynamic. What is the proper ediquette for this situation?
