First of all, I'm glad that you took up for your wife and didn't let her berate your W- your W should ALWAYS come first.
You are both young and (like so many of us) ignorant of what makes a great marriage. Like many guys do, the second you got married you stopped making an afford for her and took her for granted. Additionally, you moved her in with your family who treated her awfully. That showed her that you didn't care about her, and that you wouldn't protect her. OUCH!!!
My advice would be to man the heck up. Show this woman that you are a man that will protect her (not only from your family, but also financially) and that you love her so much that you will never take her for granted again. She probably has some very deep rooted abandonment issues that have been triggered, and you must do everything possible not to trigger those again. I would make evey effort to fight for this woman if she is indeed who you want in your life.
Only a year ago she chose to spend her life with you. Prove to her that it wasn't a mistake- you ARE the man she thought she'd married.
