Sky must still have "fat girl" mentality,
She's too cute to be worried about what he is doing. HE looks like a tweaker that got clean. Why play games with him? For one reason or another, they will break up eventually. Anybody actually think they're going to get married, have babies, and spend their lives together? LOL! No. He won't ever do that with anybody. I guarantee it. She is wasting her time with him.
She could do better. Bianca is pathetic and it obviously makes her feel good to think that she can get this guy to leave his girlfriend for her. But Sky looks kind of stupid, too. She could dump him and find someone better the next day.
How these girls don't succumb to exhaustion after running behind these losers for years, I'll never know.
