is he or isn't he.....

I'm trying to decide if this guy I know is family. Certainly every time I see him, my gaydar goes off like crazy. But he has a girlfriend. I've never met her, mind you. Just heard of her. "Girlfriends" tend to screw up the 'dar like geese getting sucked into an airplane engine. I'm just not sure. Is he in the "let's flip pronouns" phase? Say "her" instead of "him?" It's no skin off my nose. Just drives me a little crazy. Cause my gaydar is usually pretty accurate. So this weekend he and his "girlfriend" went out of town. For the first time, he mentioned her name...."Val and I are going to LA this weekend." WHAT THE FUCK! An adrogynous name! I'm no closer to solving this mystery than before.
