I am not sure if it's love or lust??

Time is always the key... lust gets old love doesn't... if he's not right in time you'll know, accept it, & be ready to move on that's what's happening to me right now

Sometimes you just know that your feelings are superficial and not sincere, but at other times things are more complicated. I guess that you can't do much more than give it some time and see where this relationship is heading towards.
