Need advice on something that makes me a horrible person (long post)

First of all I didn't really know where else to post this as I'm new to Reddit so I hope you guys on here can help.A bit of background on me, I'm a 22 year old very introverted guy, with no real relationships in my life apart from family and about a year ago I created a Kik account to help with a tumblr blog I created. On this account I used a fake name and kinda created a fake person for this account who was more extroverted and had relationships both friendly and romantically.About 6 months ago I met this guy using tumblr and we started to talk on Kik, which I used the fake account to chat with him, because I honestly didn't think it would go anywhere. You know he might talk for maybe a week or two then I wouldn't hear from him again. But he wasn't like that, to this day we still talk almost every other day and we have started to become more romantic.And the reason I'm posting this and the thing I need advice on is how do I tell him that he's basically got to know a liar, nearly everything about me, with regards to my name, friends and relationships have been lies. I know it makes me a horrible person especially since he's such a great guy, but I can't think of a way to tell him without hurting him.If anyone on here could give me some advice I would be grateful
