My LTR kind of randomly started talking last evening and said something along the lines of "you're so hot." But then her face changed and she started going on about how she should be worried, other girls will/do want me, they'll "take me from her" etc. that sort of stuff. Her demeanor and expression/nonverbal was serious.

Lol so I assume I'm doing things right, but what does it mean and how do you normally react? I just kind of dismissed it like "sure honey" or whatever
