My friend disappeared ???

I had a friend who got married to a girl. We used to keep contact through Facebook since he was in another country. The girl he was with suddenly took over his Facebook and changed the name and everything to like a joint Facebook. She also deleted all the girls from his page including me. I’ve tried asking her for him but she’s extremely hostile, and I assumed she was just super jealous. So I left it like that to not cause problems between them. Anyways, a few years have passed and out of curiosity I check her Facebook, and she no longer has any pics of him and everything is just pics of her, partying, with friends etc. I tried to look for a different Facebook with my friends name and found nothing. I looked for different social media with his name and nothing. For her in the other hand, Ive found Facebook, Instagram, and Twitter. While her Facebook is private, she has her Instagram public and twitter. I was seeing she celebrated her birthday recently. There was not one picture with my friend. It was all her, with guys and girls, and partying. As of now it’s like he’s completely vanished. I haven’t contacted her asking for him since the last time I did she was completely psycho, she insulted me and of course did not tell me how to contact him, as well as I’m sure she never told him I tried to contact him. So I have no idea what happened to my friend. He used to be very active on social media, so it’s weird to me that I haven’t found a trace. I’m not super concerned as to send cops looking for him, Its just weird to me.
