Must I spend the first days of Eid with my husband's family against my will, given that I never see my husband in his family's home?

We advise you both to be cooperative and not to differ. We advise the husband to enable his wife to visit her family on the day of Eid, while he spends Eid with his own family, as long as this brings her joy. If he insists on refusing, then she must obey him and not create a problem over this simple matter. She should speak to him gently and kindly to reach the best solution.
