Fatal Attraction (aka women are crazy part 2)

I went out on a date with a girl one week ago yesterday. It was fun. We saw each other again a few days later for a brief dinner. It was fun as well. Friday she came over for pizza and games. That too, was fun. Saturday, however, was weird and is going to force me to take immediate action. We had no plans for Saturday. I was doing my usual Saturday morning cleaning and in the afternoon headed outside to do some yardwork. When I came in and cleaned up, she expressed through text that she was surprised my work took that long. I thought to myself why should she be concerned how long this is taking me, we're not doing anything. But then she offered to come over and "reward me" later. It was cute but boxed me into a corner. Should I say yes, I've had enough of you don't come over and risk ending the relationship? I suppose I should have. But in a mistake I caved and allowed her to come over. After working all day me evening plans were to watch the Sox game and smoke. Making snide comments about both it was clear she wasn't interested in that agenda. Bottom line, seeing someone 4 times in one week is excessive. Before anyone gets the impression things are getting serious, things should be ended
