It isn't easy dating the man who played Harry Potter -- just ask Rosie Coker, Daniel Radcliffe's girlfriend of nearly two years.

"I'm not an easy person to love. There are lots of times when I'm a very good boyfriend, but there are times when I'm useless," Radcliffe, 22, tells Parade.

"I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things -- fantasy football, most recently. And she listens to it, and she loves me for my oddness, my awkwardness, all of those things that I hate about myself."

That's good news for the Woman in Black actor, who says he "hated" the idea of dating around.

"With Rosie, I didn't know what was appropriate, like on which date you're supposed to try and kiss her," he explains. "I went to kiss Rosie and at the last minute lost my nerve and ended up kissing her neck, which is a very intimate place to kiss somebody on the second date. Fortunately, she just found it really funny."

Radcliffe, who met Coker, a production assistant, on the set of Harry Potter and the Deathly Hallows: Part II, tells Parade "every day seems better" with her in it.

"Ultimately, I think it comes down to that -- having somebody in your life who makes you happier than you thought you could be."
