As a married woman, I’d say leave ASAP.
Your mental health is most important to a fulfilling life.
People marry the wrong person every day. Divorce is the way out of this situation. Judges are more realistic today about women and their plots.
Write down and document everything. Find a couples therapist so you have on record you are trying to make the marriage work for everyone.
The therapy will either make your wife “grow up” and perhaps better your relationship or it will show her inability to deal with reality of marriage as a working relationship.
Don’t be the guy that hates his life. There is the right person for you out there. Take that first step for your own sanity.
Her parents can help her out financially. She knows this too!
