She could be just trying to control or whatever, but put those feelings aside.
Lotus got it right - get help for her. Seems like something dangerous. Having kids, don't we learn there are a million ways for them to kill themselves? Much truer for adults. Why take the risk and then have kids trying to understand how life could be so bad one would have no hope? Can you get a free counsellor in your state?
In a way, feel better about yourself today. Yes, your negativity may have brought her part way down this path, but equally likly, she may have always been on it and she's lucky you didn't leave. Just because she yelled today doesn't mean that she won't thank you later...
Her father's a convict and you didn't sound too respecting of him, so why call?
You are NOT at square one. Maybe she's feeling you are becoming so good, but she's getting worse. Your KM problems sound long-term, but not all or nothing. For example, she said she touched you and didn't feel anything. That doesn't prove anything except that M problems take time to solve.
Word of caution. If you really think she would've needed a 911 call had you not opened the door, you both need counselling. Until then, try to make sure you: - aren't verbally abusive (think custody) - aren't crying and emotional around her (think blame) - aren't going 'dark' (focus on you, not ignore her)
I hope that something I wrote has some value. Remember to pick and choose with all of our advice to you Gman, only you are living your life.
