Well, some WG's do claim to have problems finding boyfriends who don't have hangups about what they do for a living, so picking a punter is a logical choice.
I'd say go for it, but be VERY careful. Don't abandon all the usual precautions against nutter WG's, never give her your real name, always call her on your unregistered punting phone, never meet at your place, and so forth.
Eventually you'll have to start sharing genuine info, but not for a few months. If things go really well, try to avoid letting her know what her new surname is going to be until you're walking her up the aisle!
