Most Helpful Guy
I think there are many warning signs that jump out at you on the first or second date, like someone who is so needy and desperate that they want to start selecting boy names and girl names on the second date, or they are extremely liberal and you are extremely conservative, or they are atheist and you are Christian. In fact, I think most of the problem signs are probably obvious within 1-2 dates.
There are some things that may takes many months to surface, like a woman who can never say "no" to her adult children, or a guy who disappears for 3 months during hunting season.
So. . . I think if a girl passes the test on the first 1-2-3 dates, the odds on her becoming a serious LTR go up substantially, but, obviously, there is much more to learn about each other before you say those three little words that every girl wants to hear: "let's go shopping!" Just kidding; the real point is that you should date someone for at least a year before considering marriage or living together. Sticking to that standard will potentially save you from some messy breakups down the road.
