anabus,
How many lies has he told you..... and how may times did you believe him?
So you think he'd KNOW if you reported him to the police??? You mean, you couldn't say that you didn't?? You know, "That's my story and I'm sticking to it?". You can't lie one time to protect yourself? Because in all honesty, I'm sure there are more people than just you who knows he's got a warrant out for his arrest. And I'm sure the possibility does exist for it to be someone other than you. And as long as that possibility exists, he CAN NOT for certain say it was you.
Just act surprised! And don't do it right after a fight. When things are cool, just do it. You could save someone's life on the road, his life, or at least your own.
