She sent me an email yesterday morning at 6am asking me if I was still awake. That's all the email said.

Her not sleeping would indicate a mania phase, right?
When I sent her an email telling her I was confused why she contacted me, she replied "leave me the f--k alone. I met the man of my dreams and I just wanted u to know that last night".

Any thoughts on this?

Also, I found out her new man has multiple arrests. Domestic violence, assault, threatening, and a few others.

She is studying criminal justice at a local college. So her involvement with this guy is totally out of character.
