Well, from what you have mentioned before, it sounds like you are pretty familiar with some of the guidelines of the church. Such as not dating until they are 16 years old and such. But the answer to if you have a chance with him, is that it really depends on him.  
 
True, we are encouraged to date within our own religion, because of the standards which we have, like abstinance before marriage. But also it is because of the blessings that we are able to take part in if we are worthy and faithful to those standards. Those blessings are given inside our temples, and the one most talked about is that we have the chance to be married "for time and all eternity" rather than "till death do you part".  
 
There are people within the church that do date people who aren't part of the Church, but that really depends on each person's individual choice. (as does everything :P ) So I guess the only way to find out is to go and ask him what he feels about it.
