This guy is my friend's ex. She dumped him before x'mas, but he won't leave her alone. Part of the reason why my friend wanted to dump him, 'cuz he was trying to smoke pot at her place. And another thing was, he never be able to get a stable job (and he never learned why he always get fired), but he's thinking ahead for marriage.
The day after he posted that up on Craigslist, he went and stalked my friend while she was on her way to work, and beat her up for leaving him. She gave him a chance for not calling the cops the first time, but he attacked her again on the following day. Now that she got a restrain order from the court, so whenever he is within 100 feet from her, he will go to the jail.

At this point, he still won't stop harassing. He had been using different phones to call her, using freetext service to sms her.

What a dysfunctional jerk - the world is filled with them.  You don't give people chances like that.  Humanbeings are creatures of habit - some have good ones, some have bad ones - and just like Zebras - don't change stripes.
