Does Anthony honestly regret the decisions he's made up to this point?

Ian and Anthony are finally on college. But in the instant the stepped in, Anthony changed, now he flirts with every girl and bangs everything that moves almost every night. Ian has really strong feelings for him, and after a little incident (not so incidental) for a second thought that Anthony had the same feelings for him. Maybe he does, but he keeps hurting Ian again and again. He never realizes that until a really 'hot' guy steps on Ian's life. Now Anthony's jealouse and mad. He'll do anything to get Ian back...or not?
