this girl is dynamic outer enviroment. you cannot control what she does but you can control your own reaction to the situation by giving her the insincere gesture of kindness. you need to be objective. perhaps you need to join some new groups or find other ways to make new friends, in the event that she no longer wants you. plan, decide, and act, based upon being the objective realist as opposed to the romanto-intellectualist. don't just sit there and remain in duality. even if you decide temporarily not to decide about where this relationship is going, at least broaden you horizons a bit for the time being.
