We are getting married this weekend. My FI's best friend just announced that he is bringing his 3 year old son with him this weekend so that FI can "spend some quality time with him". We are not having children at the wedding and he expects my FI to spend time this weekend hanging out with his child. I think this is horribly rude and selfish as this is hardly an appropriate time for this. We are going to be so busy with in town family I'm speechless. Now he tells us he isn't sure if he can make it to the rehearsal because he has his son with them. Then he is staying in a hotel 40 minutes out of the city and insists that FI drive to his room after the rehearsal dinner to spend time with his son. Am I the only one who thinks this is insane? What are we supposed to do with this?
