Hy Daniella,

First of all to answer your question. You aren’t doing anything wrong.
You did your best by leaving him alone while he was depressed and while everything went down for him because he wanted to.
He needs to find himself why everything of that happened and learn a lesson.
What you did is gave him one of the greatest lessons in life (aka tough love) because right now he might feel desperate and depressed but eventually he will either kill himself (which is less likely) or stand up and start learning about himself which is the only way of learning about life in general.
I was jealous and depressed all the time during my past relationship which ended bad (I’ve developed depression, anxiety and OCD) because of ME and only Me (maybe she was also doing something wrong but who am I to judge, right?)
Now I’m trying to do my best to become mentally, physically and emotionally strong enough and mature enough to step in a serious relationship where I’ll do my best to share love and be loved!
(Sorry if I spelled something wrong or grammar isn’t right because English isn’t my first language)
Hope you find this answer useful and all I can say right now is:
Chase you dreams and help your family while you still can!

Best wishes,
Karlo
