Here you are, already making excuses for someone who has no business pursuing a relationship.
Drop the asshole. It's not your job to mommy someone who is emotionally retarded. That's not what relationships are about. I had a cancer pull some dumb shit via FB. I blocked his ass, it was such a turn off.
You need to grow up and learn to identify when it's pointless to pursue someone of such immaturity. He'll only learn if you don't enable.
