Will he and I last in this relationship?

Hi, there is a chance for your ever-lasting relationship. You are attracted to each other by the sense of curiosity. So you generally get along well. As time passes by, when the mutual curiosity declines, you may confront some difficulties in cmmunicating and understanding. Under these circumstances, you should be more considerate and supportive to each other. Then you will stay together for long and even can expect marriage.
Best wishes~
