I got married 3 months ago. I am 27 and my husband is 32. I have seen that my sister-in-law is a bit weird. When we go out, we share pictures with our families since they never get a chance to accompany us. My husband would send her the pictures of us visiting various places and asks her to show it to his parents, but she never does that. Mind you, she is a 24-year-old girl, not a baby. If the same event happens multiple times, it cannot be considered a mistake right? Also, my husband is not ready to accept her fault. How do I make him realize the damage she is doing by creating a gap between us and his parents? I can clearly see she is trying to create misunderstanding between us. Please tell me how to handle this situation.
