Truth #1 - You've known her for 6 months and haven't dated, but you've "talked about getting together sometime in the future". Dude, you aren't even at 'Friend' status.
Truth #2 - She was accepting you're wuss-like advances much like any employer...especially one getting free services, would. However, when you screwed up her plans, you are soooooo fired
Truth is she never intended to have a relationship with you and was stringing you along taking advantage of all the freebees she was getting from you. To her you were just another wussy-nice-guy who slobberred on her heels and kissed her butt for some false hope of "maybe one day we'll be together." Just another attention whore getting her jollies off by using someone who was somehow mesmorized by her good-lookingness.
