Pretty sure they're only still together because each other is all they know, Alex has probably thought of leaving many times but stops himself by looking at what he'd be giving up.. money, huge house, freedom to not have to get a proper job. Sadly these things seem to be more important to some people over genuine happiness.
Totally agree!. That's why I don't feel sorry for Alex. And unpopular opinion, but I don't think is Victoria's fault. Everyday he is choosing the easy money, the first class trips, the luxury hotels, free clothes, free shoes, free everything, cars, houses, he chose that over his mental health.
They don't have to divorce. But if the guy is struggling he should stop working with Victoria. Not travel with her. Let her do her thing. Get a job on a company where he has contact with other people, get a routine and work on his mental health. Victoria earns a lot of money. He is free to get whatever work that makes him happy without the need to get an amazing salarie. Basically he can get a new job just for fun!.
But that's something I don't see them do for the good of him and their relationship.
I see Alex denying to quit all the easy money. And chossing to complain how unhappy he is. As you said "Sadly these things seem to be more important to some people over genuine happiness".
