Is it time to shunt a pet squeeze when the matter shifts from "purely physical" to having "feelings for you"?

Man I dont get this chic. Following ya all Yahoo folks advice I reformed myself and went down the honest path telling my Blackberry harem of gals that I was not into commitment but just getting batting practice. Still many suicidal die hards jumped in and I pumped with a clean conscience, until the other day .. I mean night. This gal traversed the whole gamut of the science department from "purely physical" to "somewhat biological" and "immensely chemical". Now she says she is starting to have feelings for me and wants to "know more". Whats more to know, she already knows the length of my enchilada. Is she trying to get me bamboozled? Although this squeeze is surely sweeter than a melon and smoother than silk, my radar is not comfortable and I suspect she will turn in some nasty moves. Should I bail out before she goes psycho? Whats the best way to do it. I didnt mind when all the feelings were confined to a vibrating uterus. But this ... please help .. it was your advice Yahooligans.
