What acts are considered idenity theft?

My (ex)girlfriend was able to log into my email and my bank account by figuring out my passwords. She didn't spend my money or send out spam under my name but I want to know if this is considered identity theft. Can I have her arrested for it? By NoExcusesAny time someone uses another person's identity for any other purpose, it is identity theft. In your case, I don't think you can have her arrested but she can receive a warning. While setting passwords never use anywords or figures that would make sense eg:your name, birthdate, special dates, children's names, spouse's name, etc. Use some vague words and figures that only makes sense to you and mix them up.
I suggest stronger passwords that impossible to ' guess'.
