My mother-in-law has not spoken to me since my engagement ceremony

Although I have been married for only four months, my relationship with my mother-in-law is not as I had envisioned. It began on the day of my engagement. Amid the bustle of hosting guests and the ceremonial preparations, I noticed her apparent unhappiness. She did not speak to me at all, despite my attempts to initiate conversation. Initially, I attributed her silence to exhaustion from the event’s preparations, but it soon became clear that the issue was more complex than I had thought.

Following the ceremony, I hoped our interaction would normalize, but her silence persisted. I have tried to uncover the cause by asking my husband to speak with her and seeking insights from other relatives, yet no one seems to understand the problem. I am left wondering if I inadvertently did something to offend her.

Furthermore, my mother-in-law once expressed feeling a sense of loss when her son married, which may be contributing to her current demeanor.

The ongoing lack of communication has made daily life increasingly stressful. Family meals and gatherings are now tense, filled with an uncomfortable and chilly atmosphere that leaves me feeling trapped.

How can I improve this situation?
