He's probably upset that he has trouble with women who are attractive as you are, so he has to put them down to make himself feel better, and also troll. He knows you're attractive, it's the internet, and wants to troll to ruin your day. You kind of gave a him a reaction he wanted to by posting this, not to say you shouldn't, but I'm sure he wanted this.
there are so many possibilities ranging from he likes you to he hates you to he's bored. you'll never really know the real reason & you don't need to waste your valuable time on useless messages. just ignore it and continue with your life.
Sometimes people get a kick out of being a douchebag on the internet because they are a... douchebag, haha. Least you know that's a lie! You are a very pretty girl, beautiful! No point in answering a troll!
They are hyped up on hatter-aid. They have nothing better to do than to sit around and judge other people. The funny thing is he doesn't have a pic up. He probably knows he is ugly now he is calling someone else ugly. You are really pretty. Don't let him bring you down. Please!!!<3
