It was devastating for him, it was very strange, Nelson was relieved but the peace won't last long, she looked good, she was impassive, she was very intelligent and manipulative, she didn't give the impression she did to anyone, he didn't noticed that Sheila was obsessed with her.
I'll find a way to get Nelson back, so if that means being with him, being friends.
He stopped with all his other conquests, to be with Ana Lise, the Don Juan, he gave up his conquests for something more solid.
When a man takes his girlfriend to meet his family, it means, he is more committed to the relationship, they are more committed, they become more solid, whereas Sheila was obsessed.
