In-laws and infidelity

Think hating your mother-in-law's lasagna is a matter confined to the kitchen?

You could be wrong.

Here's some interesting news about a study that suggests a bad relationship with your in-laws might make you more prone to infidelity.

I understand the reasoning: weak ties with your partner's extended family could mean you're less invested in your relationship, heightening your chances of straying.

But at the same time, I know plenty of people who despise their in-laws but are completely committed to their partner.

Weigh in: If you can't get along with your in-laws, is your relationship destined to fail?
