Being positive in negative situations is hard, but still vital. It becomes all the more important when the people who are supposed to be leaders fall into negativity. Don't let them drag you down. Lead the way when they can't.
the actions of moving on to flirting with another man, should be a big sign that she's just not into you - this "love" she says afterwards, after she got dumped, isn't as authentic. . .as well as planning a "magic mike" girl's night out four days after the wedding - maybe four months, but not four DAYS after! that's just total disrespect!
