I had this problem before (and lots of stalkers). This used to be my sticking point but it's no longer a problem. The best way to address this is with a proper Exit Strategy. You don't have to lie or say you love them too. Since girls too often confuse lust with love, you're actually doing them a favor when you bang them.
So your Exit Strategy is to make them fall out of 'love'. How? Do the opposite of attracting them.
For instance, instead of giving them the eyefuck, look down and act non-dominant. Brag. Be needy. Be a super ultra-AFC. They're gone in no time. Of course, since they had great sex with you (make sure you give these girls the greatest sex ever), they'll always come back for more great sex. You'll just be a sex object and not a boyfriend material anymore.
However, the one girl who sticks with you through thick or thin (when you're alpha and when you're ultra AFC) not just for sex, then that's your 'true love'. Take care of her. Those girls come rarely. Make sure that 'one' girl didn't have a boyfriend or husband when you had sex the first time. When they're super hot about you, girls will lie about having husbands/boyfriends just so you can bang them. These types are not the 'one.' Just saying.
