That sounds like it was written by a 12 year old. The guy I was talking to is 28 and still a virgin. I have a friend who weighs over 300 lbs, works part time for minimum wage, and takes medication for mental health issues, and even he has a girlfriend who lives with him. Anyone can have a relationship if they have realistic standards.
That anyone can have a relationship is obviously bullshit. The evidence shows that definitely not everyone can.
The only people who can't have relationships are those whose standards are too high. Most guys who "can't get a girl" are really just chasing after the ones who wouldn't give them the time of day. The Jonah Hills of real life don't get the Emma Stones.
