Don't let him get to you. It hurts so much to here because you ARE letting him get to you. People call me a "faggot" all the time at school and you know what I say to them? "Thank you for the compliment." Just because he likes being an ass, doesn't mean you have to feed into his bullshit, my friend. If he says something bad to you, just ignore him. He's not worth your time and effort if all he's doing is bashing you about yourself when he has yet to look at himself. And if he hates you so much, why does he call? If he hated you as much as he says he does, why take the time to call you? That confuses even me. Like I said, hes not worth your time and effort if all he's going to do is bash you about your sexuality. Don't give that bastard the time of day, my dear friend. That bastard of a sperm donor isn't worth it. If you feed into it, it's just going to continue. Next time, if he calls using your mothers cell phone and you hear his fucking voice, Just hang up. If the number pops up again, answer. If it's his voice, hang up. You don't have to listen to his bull shit.
He isn't worth your precious time, nor your loving effort.
