I was wondering, have you ever had that kind of experience with a girl where she claimed she was pregnant or appeared to be lying to get pregnant or so on? I know it's a fear that a certain proportion of men have. I haven't experienced it but then again when I date women I don't have to worry if they will get pregnant. While I am sure that it's a thing that happens, I am not sure it is so common that one must be a good judge of character to get through life without experiencing it. I am just loath to believe it is a danger one must side-step at every turn when dating women. Certainly having that attitude would make relationships harder I think.
I also refuse to get romantically involved before I judge someones character. I found my boyfriend online and screened him pretty carefully. I said I would only date guys with a job, house, and masters degree. I worked backwards from there, seeing if we got along as people. Dated too many musicians, to believe in fairy tales. My credit was fucked by guys using me, so I won't date people anymore who don't wipe their own ass. This attitude works for me and makes my relationship easier, instead of harder. I don't know if I would have gotten to this point as a guy. They have too much instinct to be irresponsible with getting girls pregnant. For a guy to be like that, he would have to be very driven, or seen some awful situations.
