A story to tell the grandkids: Our first date was average, nice and casual, quick hug in the car and neither of us wanted anything more. But I figured I wouldn"t have had a problem hanging out with her again, but wouldn"t care if I never saw her either. So, shrug, saw her at a party later in the week and why not, right, still wasn"t sparks or chemistry, but it wasn"t bad, at least, still really casual and comfortable, and the conversation kept flowing despite little common ground (it"s why we still just talk about things we"ve seen on tv, kids). I had nothing to complain about, and, eh, why not, right, so we built a life together. It"s been an... average life, no real highs or passion, but hey, not a disaster either. A nearly apathetic recognition you have nothing to complain about.... that, kids, is what you should look for in a significant other.
Duuuuude, even Mormons have more exciting first-time-meetings than this shit. Even if it"s just a formal handshake and laughing when someone says "Oh Gall!" a little too passionately, they at least FEEL something for the boring things they"re doing.
You"ve found yourself in a dangerous catch-22. The only way you should still be into seeing this boring chick again is if she"s really hot. But if she"s really hot, you should be interested or excited. If you"re not gay and looking for a see-I"m-not-gay woman to marry for the sake of your parents, then why the fuck bother with this shit?
"Eh, why not?" If it does work out at least never tell HER that"s how you felt. There shouldn"t be instant, deep, unconditional attraction when you first meet someone... but you should be something more than "no complaints."
Only thing worse than being friend zoned is this sort of situation. You"ve been on a date. You hang in similar circles. Eventually you"ll just sort of find yourselves in a relationship because "eh, why not" and it"ll be boring as fuck and the worst kind of settling (worse than "I want babies, so I guess this is my chance" as it"ll just be giving up on finding someone that IS actually interested and passionate). It"s like a friend-zone where you"re bound to monogamy, and I recommend staying away.
