My cousin has put on his Facebook that he's a women and such

So earlier my grandparents and parents were talking about how my cousin,who is in his 20s and he's happily married to a women, has put in his Facebook profile that he's a women and so on. He's actually has gotten a ton of encouragement and such from friends and his wife's family but my grandparents/parents/ his sisters are all weirded out and wondering if he's messing with ppl or is messed up in the head. I didn't say anything cause I didn't want to deal with all the anger if I did lol. Was wondering to you guys if he's acting or if he's actually a women in a mans body and is just now realizing it and coming to terms with it? He acts just like a women and so on from what I e seen from the few times Ive seen him. Don't see him that often since his wife doesn't like us for reasons unknown but thought if he's going through all that and I'm gay then maybe we could have at the very least a friendship or something maybe. Not sure if I should ask him directly thru fb or leave the subject alone for now what do you all think?

 

Sorry if I offended anyone for saying he instead of she. I wore it while I was still a bit shocked over him being a she after all the years I've known her if that makes any sense at all? I don't care one bit about it and I'm happy for her finding herself and everything it was just a bit shocking is all lol besides if I did care about that then that would be hypocritical of me now wouldn't it? So sorry to anyone if I did offend them for anything I said or worded. Thanks for all of the suggestions xD. Now to wait and see if she will answer me or not.
