Is it reasonable to dislike a partner's family?

Sometimes yes. If your family is toxic (abusive, dysfunctional), a healthy partner will want distance. If your family is just different in style or values, the partner must try to accept them. Red flag: your partner dislikes your entire family and isolates you from them. Green flag: your partner dislikes specific behaviors and sets healthy boundaries.

How much time must we spend with family?

This requires explicit negotiation. Cultural norms differ widely. Some families expect weekly dinners; others expect annual visits. A compatible couple agrees: "We'll visit twice yearly" or "Holiday and birthday occasions." Both need to feel the arrangement is fair and sustainable.

What if my partner's dislike of my family is causing tension in our marriage?

You need to make a choice: (1) accept your partner's boundary (limited family contact) and manage your family relationship separately, (2) ask your partner to reconsider and work on acceptance (therapy might help), or (3) recognize incompatibility if either side won't budge. Many marriages end over family issues—make your choice clear early.
