she just goes for it, even if the prospect of a stable, secure life with him looks murky and uncertain (to outsiders). That is, even if what she has is less than ideal (to outsiders), she's optimistic that maybe it'll all work out fine in the end.
And I wonder if that sort of hope-for-the-best attitude is an SP thing. I kinda envy that lack of worrying, the fearlessness. I'm impulsive when it comes to relationships as well, but the moment a red flag shows up, my tendency is to drop the guy like a hot potato (hence I have a few one night stands behind me). I think of all the reasons why it can't work out, whereas the SPs I know seem to do the opposite.
As to how it relates to Bamboo's predicament, I think it's great that he's starting to identify a pattern and aware enough to want to do something about it. While in the present moment, it can seem exciting to have the attention of a taken woman, and things might seem swell, one must consider the past and future too to have a more complete perspective. As other posters have pointed out, it's good to know what YOU want - that's the future, and this knowledge is often guided by the mistakes and lessons of the past to determine your actions in the present.
Anyway, what I want to know is where are all the cute, smart, SINGLE girls in your area, Bamboo???
