Think about it like a cheesecake sampler, each slice a different flavor. The slices are representative of the guys she is dealing with. When she is done consuming one slice, she wants to experience something new, so she reaches for another flavor. In other words, most of these women have a rotation of guys and you were the one she sampled for a little while and once she's consumed enough of you, she reached for something that tastes different. It's not always necessarily something you are or aren't doing. Sometimes it is that particular woman's need for variety that causes her to take a dose of you and then to move on to another plate. A lot of times these women will be cool for a few weeks, disappear for a couple of weeks, and then pop right back up. When that is said and done, she is coming back for seconds after sampling another man, but it depends on the level of dignity you have whether or not you will satiate her cravings.
