[Fantasy Lore] can a succubus fall in love and if so, how would I know she's not just leading me on to eat me?

Succubi *can* fall in love. Often they show their true feelings by swearing off other men (basically like if you starved yourself turning down all these delicious cheeseburgers because you wanted to own, but not just eat, a pizza), ignoring their sexual desires and playing the slow game with you not to blow it, and emotionally opening up to you about their feelings but not expecting anything more than say a hug, kiss or hell even just a verbal reciprocation in return. 

Most likely you're going to need to understand why they're in love though. If you're just a hot guy, then chances are you're just dinner. If you've been good friends with her, made her laugh and protected her from harm (like the bond between a certain blue haired succubus and a brainless brown haired human) then it's much more likely that you're more than a snack for her.
