How shall I confront her? She remains nervous to talk except gaze. Because mostly we happen to strike at family partie. What to do?

Kindly throw some light on this

This newly married girl that I have known for a while dead gazes me even before her marriage and until today when I spot her in functions and parties, Her husband is mostly present in and around. Even when she's caught by me she still doesn't give a fuck and continue to gaze.
It was a dinner party. She wore a sheer yoga pants and full sleeve shirt. My attitude towards her has been mostly ignorant. The limits crossed when she came next to me In the family photo well I stood last and her husband was on the far other side people asked but she refused to leave beside me. What was going in in her mind?
