My mother-in-law makes sarcastic remarks every time I visit my parents

I have to say my mother-in-law is quite tactful, since she only expresses her sarcasm when my husband is not home, as if she wants me to know she’s displeased without letting my husband find out that she does so.

Even when I return to my parents’ home for only a few days, she remains unsatisfied. Although I don’t catch every word she says during these times, I can sense her displeasure through her sarcastic and cutting comments.

My mother-in-law has a daughter who is married and lives far away, so she might understand the feeling of missing a child. Yet, she has never put herself in my shoes to empathize, which saddens me.

The resentment and sadness within me grow each day, but I don’t dare to confide in my husband. I know he loves his mother the most, and if I were to discuss these issues, he might scold or blame me rather than offer understanding or sympathy. I don’t want to hurt him, and I’m uncertain about how to handle this situation properly. I feel lonely and lost.

What should I do in this situation?
