Should I tell him I'm a stalker?

[Jeremy]

OK so I have a boyfriend...yay go me!!! He thinks we met randomly at this pub and got to talking and then starting seeing each other. But there is something he doesn't know.

I saw him randomly at a pub about a year ago. He was gorgeous...I fell in love and found out his name but didn't have the balls to talk to him....so I stalked him through facebook, twitter, by asking random questions to some of our mutual friends etc....I knew he was going to the pub one night so I went there to see him...

So basically we never randomly met. I stalked him learnt a couple of things about what he liked (bands and art) and struck up a conversation that way. I feel like such a weirdo and a creep (and ok yeah i am) but my question is....

should I tell him that I basically became obsessed with him? We're happy together but I feel like I am keeping this huge lie. If you were in his shoes and found out would you leave me?
