You know, there is a tendency toward paranoia and suspicion that I've noticed amongst many of us Pakistani women. We over-complicate things. And sometimes it's legitimate and sometimes it's not. But there's no reason to assume that your relationship with your MIL will get bad, just because a few narrow-minded, jealous, or pessimistic folks say it will. They may put in seeds of doubt (even if they don't have malicious intent) that can ruin a relationship for no reason. So just nod and smile, and remember that nothing can ruin the relationship unless you and your MIL let it.
