Do you like him? Do you like his language, midos, character, actions? If the answer is yes, I don’t think you’ve got anything to worry about. (Don’t jump to a decision, of course)
First of all, when you fall in love, you don’t necessarily like the person (you may like their appearance). I think love is blinding (I’ve seen it happen with me). So in a way, you’re lucky to look at it with clarity.
Secondly, do you know him? You may think you do. But it’s nearly impossible to really get to know a person in a few short dates. When you live with someone and get to know their true values, you may end up really loving and respecting them for who they are even if you didn’t have “butterflies” at first.
