Is this a good match? Is it the right move to hold on to him?

In early June I met a man (we will call him Joe) born 5/23/1986, my birthday is 11/12/1986. We get along great, he really pushes me to stay open and communicate with him. We took things really slow not making a commitment because we knew I would be moving in August to go to school. But now that I have moved and gotten settled and gone on a few dates with other men I find then shallow and rude or immature and often go home and call Joe and spend hours talking to him. He says he is going to come to see me for my birthday.
