He wants you badly.
Go hang out near that bathroom (don't let him see you) and follow him home so you know where he lives.
Then drive by his house real slow at least 4 or 5 times a day.
Try to figure out when he goes to work and follow him there, so you know where is is during the day.
Rent a car with tinted windows and sit outside his workplace wearing a disguise and sunglasses, so you can see where he goes to lunch.
Get a different car with tinted windows to sit outside his house at night, to see if any other women show up, then follow them home.
You'll know what to do with them.
He's yours, just remember that.
If it comes down to it, keep in mind if you can't have him, no one can.
Here's a good disguise...he'll probably just think your a dog.
