The couple were caught Поцелуи each other! check out the pics here on Fanpop. Went on a дата at I HOPE, also check out that pic online!
If he loves Selena, why wouldn't he just admit it? My guess is that he's afraid he'll loose his fans, Selena will be hated by million of girls, & no one would by Justin's Album.
U know how Justin always skips the Вопрос "Do U have a girlfriend?" during interviews? Thats a clue beliebers!
However, If you're truly a belieber, U would be happy for him cause he's happy :)

Peace!
