People should have common interests or at least be supportive of each other's interests. We are constantly adapting, so adapting to fit well with another person isn't really unheard of. It can be a good thing, as long as you don't lose the core of what it means to be you. Time can tell you if you have enough in common. Do you enjoy each others company? Do you treat each other with mutual respect? Is there honesty? Does the other person love you and have your love in return?

I think you should call him. If he's as sweet and wonderful a person as you believe him to be then go for it. The juvenile humour my mother would say is kinda a guy prerequisite at times. Give him another chance then make your decision as to whether he's the one or not.
