Moved to US from civilized country despite reservations.
Reliant on person with mental health issues and others you don't know.
Nobody to aid or contribute financially. No welfare system for you.
Now being abused and understandably hating US.
Despite desperate situation, had the presence of mind to evaluate additional. relationship.
Sorry, imo, thinking it through would involve acknowledging how many shades of wrong this could go and either not going or setting provisions for disasters. Sounds like you were in love and went with it.
