You're only a fangirl if - when the flaws become evident, down the line - you STILL insist they're not there.
That's what separates the fangirl from the rational girl. The willful ignorance part
Being in love is wonderful. It's staying with the wrong person after the love part is over that's the problem.
Friendly bet - If I've fallen out of love with it in six months and have started to see writhing maggots under the face of my beloved PoE, I will totally say "a winner is you!". I could even give you a free copy of Torchlight if you want it. xD
But somehow I doubt it. I fell this hard for Oblivion when I first started playing (and modding) it, and it's still absolutely one of my favorite RPG's ever.
Also, in real life love, I don't give lightly, and when I fall in love, I stay in love. Momentary infatuation is for flakes. So this is probably for keeps!
