When I started dating this year, I had a couple of criteria before going out with a guy. Since I was new to this, I just looked at the status (dapat single) at educational attainment (ideally masters, college - depende sa course).
Now that I have dated for almost 9 months (yey), I can say pahaba ng pahaba ang criteria ko. Kasi tama ka sis mimiku, sayang lang oras mo if he is not someone you would want to get to know. Pero at the same time, if you don't give yourself a chance to know him, baka you are letting go a golden opportunity.
So for me, the key is balance. Ang ma-suggest ko, kung hindi naman kasuklam suklam yung guy, give it a chance - at least 1 date. And kung wala talaga. Stop from there. What I did was 3 dates pa nga eh. Pero wala talaga. And I make sure I offer to pay at times para hindi sya lagi nagbabayad at sabihin I just used him for free meals.

And be honest, para fair din naman sa guy.
One time I dated this guy kasi sobrang mapursige sya. I also did not like him initially. But guess what, after a couple of dates, I got to know him and was attracted to him also. Take note for girls kasi, sometimes hindi physical and hinahanap natin. It's the personality of the guy eh. Unlike for guys, mas malakas na factor ang physical appearance.
