I wouldn't worry about it too much if I were you. I fall in love all the time with providers. I can think of at least three I'm in love with right now, plus another girl who I knew a long time ago who is back in my life and I never stopped loving her. Nope, failing in love with providers is not my problem. My problem is finding the time to fuck all the gorgeous girls out there!!!
By the way, PFMTony had a great suggestion for dealing with girls that love you who you aren't in love with and/or don't wish to support. Fuck their sister or friends and they will hate you. Try to avoid the psychopathic ones, though!
