I agree with sunrise... just relax and have some fun with this guy, after a few more dates you'll see his true colours, whatever they are. Remember that it's human nature to put on the best possible face at first for someone you're romantically interested in, so as your bond grows, you'll both relax a bit more. Also, I know you're only interested in seeing guys with marriage-potential, but maybe just take it really slow and become friends? My bf and I are best friends, (which developed while we first dated) and that makes the romantic side of the relationship way better
