Frustrated after watching 4 episodes

The FL'story line is so confusing. Sleeping with ex bf. Then kissing ex bf still they are fnds. Using ex bf having feelings for ex bf then suddenly the guy who was testing her she start dating him. I don't think even teenagers will be this much immature. The writer was trying to portray her like someone with no true emotions and without brains.. At first it was fun then it became pathetic and slow. ???????????????????????????????????????????????????It's not at all fabulous
