Most Helpful Guy
Sure, he can find himself suddenly wanting to be with you, to see what it's like, etc. Judging by how you describe him, and my own experiences, he won't transform who he is and has been because he finds you interesting and surprising, someone with some depth. He may be showing interest to test you and see just how hard or easy you are to get. Either way, he clearly likes you and is interested. I would tell you not to read too far into it, trust your gut and don't blind yourself to who he is and has been.
