The correct answer would be, Social Commitment.
While they do not always enjoy spending time with their partner's family, they do this because of the Social Commitment.
Explanation:
When people fulfill the social demands of other people just for the sake of the commitment they made with each other, they are said to be bounded by the Social Commitment.
If two persons are committed, it is their ethical responsibility to take care of the social needs of the other person as well. Just like in this example given in the question, Patrick and Anna don't like to spend time with each other's family, but they both do it often because of their commitment with each other, which obligate them ethically to move with each other socially as well.
