I think when you really boil it down, though, it's probably only going to be Blackwall that counts as "not looking for love". Cole isn't a man, really. He's a spirit and his emotional maturity is not wholly adult. I totally understand the issue that he looks like a male, but spirits have no gender. Granted, Bioware doesn't often handle "non-gendered" well. (Asari, I'm looking at you.) Varric probably is looking for love and desperately so, just not from you. He's most likely tied up in his Bianca plot, which could very well end up being his main personal arc. So, basically, you have one human male that's not looking for love and that's because he's excepted he has barely any time left to live. He could have been one human woman the wasn't looking for love and that would have been really nice, though, don't get me wrong.
At least, that's if my predictions are correct, which they may not be.
