Wow, what a jerk.

Would you really want to be with someone who bases another's worth on such things as your career......given the fact that you're being INCREDIBLY selfless by taking care of your dad? You're doing something wonderful but he only cares about your job. He's pretty immature while you sound a bit more mature than he is. That is, you know the value of caring for those you love, he is only focused on himself.

You're better off without him.
