My cousin eloped with a man

For context, my cousin is a 28-year-old software engineer and earns quite well for herself and the man she eloped with is 29 and is jobless. I (18f) always knew they were dating but never told this to anyone as that guy was from a lower caste (her parents are kind of conservative)

When we found out about this, (A very longg story, will probably take me hours to explain) we went to his house.. and there she was looking all naive, I legit thought that pos abducted her. He said smth like he knew we'd come and started talking in a very derogatory way.. he called my aunt names and basically spoke shit instead of making truce. We then had to call the police on him.

The police let us talk to her and she looked so emotionless (i still think that guy blackmailed her with something, she has never been the type to do this). She even referred to him as her husband and refused to come home and talk this true. We had to let them go as they were adults and were married at that .

She blocked my family in almost everywhere except me. I contacted her via IG to know what really conspired. I wasn't very blatant as I didn't want her to think i was judging her. Every subtle attempt I made at knowing the truth, she ignored. She also told me that she was goin to the US due to work for a week and im so scared that that guy is goin to take advantage of her bc of her nativity.

What should I do bc I really miss her and I want my family to accept her again (they said they would only if she leaves him). I personally don't not like that guy, I think he is a gold digger and gives off playboy vibes.

This is a throwaway account. Thank you.
