So, if I can't have him, no one can, Chanda? Beyond it obviously being a sign of jealousy and (unhealthy) obsession to a degree, it's also a sign of a potential psychological problem and can lead to murder. Watch enough crime documentaries (not CSI, NCIS, Bones, etc) and you'll notice a trend with love triangles and scorned lovers. Jealousy isn't a bad thing but if strong enough ... if can lead to terrible things. While in this context, I don't see you going out to murder someone, I'd have to seriously fear for your personal life. If you fell for some cute guy in the real world and you found out he wasn't into you, are you going to throw a fit until he relents even if it would make him unhappy to do so?
While it's a disappointment Cullen's not for everyone, it's said and done. Outside of mods, it won't be changing. The writers made their decision and shouldn't be bullied into changing it nor should those who will get the change to get Cullen because they will roll a female inquisitor should feel bad because they can have him. Not everyone in real life is bisexual so why should this be true in a game? Perhaps stepping away and focusing on something else would be for the best. There are many other things in life outside of the Bioware boards. I myself float about 5-6 boards in a given day when I'm not watching TV or playing a game. One board irritates me, I have the others to occupy me for a while. No need to get an ulcer over a design decision and no need to say others shouldn't have something because you can't.
Rather than being angry that you can't have Cullen with a male inquisitor, either be happy for others who are willing to play a female inquisitor or roll a female one yourself. Don't be closed minded. Doing so is what causes arguments. Play devil's advocate with yourself. Try to see the other side. When DAI comes out, at least attempt to play the other side. You'll never know what you find.
