Why should I care?

He makes me feel like a second choice and I always have to make the effort to hang out with him. His brother and friends wouldn't want any of the girls they know to get involved with him because they know the girls would get hurt. He knows I have a new phone number here and hasn't asked for it. He's complained that he doesn't get to hang out with some of his friends, but doesn't call them or leave his house to seek them out. And he's given me a million reasons not to trust him with my heart. So, why do I even care?
