His pag-ibig life changes like any guy's pag-ibig life change. At first he loves or has a crush on Cho Chang but then when they brake up in order of the Pheonix, he falls in pag-ibig with ginny from book 6 to the last book and they get married.
Obviously. He loves plenty of people. But I'm sure you meant romantically so we all must agree that he is in pag-ibig with Ginny, even though at some point I thought he was denying his feelings for Hermione for the sake of Ron...anyways, yes. He loves Ginevra Weasley. The biggest proof of this fact was his nose! lol.
Amortentia brought him the scents of "treacle tart, the woody smell of a broomstick handle, and something flowery he thought he might have smelled at the Burrow". That something flowery was no doubt Ginny. Sigh. Yes. He's in pag-ibig with her.
Yes, he loves Ginny and his best driends Ron and Hermione and also his mom and Dad (even though they are dead) and he loves many madami people. He loves the Weasley family. and he probably loves Teddy Lupin (his goodson)
