How do I ask my love out?

What might work is a no-pressure 'no date'. Like a day time catch up, or after school or after work catch up. Let the comfort build and then naturally it will move to better dates.
So firstly, a date in a public place is better for shy people.

On another note, why date a liar? You'll just get bitter and will learn not to trust men. You may say one day 'All guys are liars! " based on your experience with him,.

If you know he tells lies then what makes you think that he thinks that you are the love of his life.

What is this? A scene from the movie Enchanted?! I half expect you to break out into song soon. Calm down. This guy is going to run from you if you keep talking like that.

Whoa, whoa, sugar, slow down. You're creeping me out and I'm not the object of your affections. He's not your husband-to-be, he's not the love of your life, if you haven't even been out on a date yet. Look, I've been sixteen, I know how it is to have a crush that is your whole life. I know how it is to write things like "Mrs. Michael Harper" or whatever on your notebook with little heart swirls around it. Pretty much every sixteen-year-old girl does that, but they don't end up marrying the guy, or usually even dating him.

But think things through a moment. If you didn't like someone, or maybe just liked them as a friend, and they were pursuing you relentlessly and obsessing over you, you'd be creeped out, right? You'd want to avoid them. Being stalkerish won't get you a guy. I think you may have lost your chance with this guy, but I'd lay off for a while and let him initiate contact again if he's interested. After all, he sure knows you're interested in him. If he's interested in you, he'll reciprocate. But it sounds like he may have lied to have an easy out from seeing you without telling you that you were creeping him out. Sorry to be the bearer of bad news, chica, but you definitely went about this the wrong way.
