Threats

I'm referring to JL's threats. He's sent me numerous threats through email, he's called me and made threats. Recently, I found where he has created a blog just for the purpose of harassing and stalking me further. It's amazing what lengths people will go to harass and annoy someone.
I most definitely fear what he could do if he found me. He's threatened me every time I refuse to answer one of his terrible emails. He'll say stuff like he still loves me then turn around in the next breath and threaten harm to me if I don't answer his emails which I never do well at least almost never. There are times when he pushes my buttons to the point where I react which I know is something I shouldn't do but I do it anyway sometimes. I try to keep my cool and not let anything he says bother me no matter how scared or angry I am.
This only serves to anger him more however but still I stay strong and try not to let it bother me although many times it does even when I don't show it not even to my family.
