One Direction: Preferences and Imagines (Tumblr)

you know he loves you when he...

Louis: ...he's always around you. He spends the most time with you than any other member in the band. He even takes you to as many tours as possible. He never wants to be apart from you, and he cherishes each moment he has with you.

Zayn: ...he stares at you. Most of the time, he'll look away, but every now and then he'll be mesmerized by your eyes and never wants to pull away. He knows that he's obvious, but he can't help himself. Just hearing your name gets him distracted, and he loses his cool.

Liam: ...he stutters and babbles around you. One time when you were within two feet from Liam, he complimented your top, but then thought that you would think he was staring at your chest so he got nervous and babbled that it's not what he meant.

Niall...he's being clumsy. Niall gets so distracted by your beauty that he'll sometimes not look where he's walking and trip. You make him nervous, and it frustrates him that he's in love with you and doesn't have the guts to ask you out.

Harry:...he gets jealous when you hang out with your guy friends. You told him that you're just friends, but he's afraid that it'll turn to something more. He wants to be able to make you all his without worrying about the competition.
