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.

there's this guy who's mormon in my school, and he's 13 and so am i, is there anyway we could go out? or can he not date til he's 16?

To the person who is 13, again the best thing I think you could do, would be to just ask the guy. Explain to him that you have heard that he's encouraged not to date till he's 16, but you would like to date him. I'm sure he would be flattered, and you'll get the answer straight from him.

as mentioned, it depends on the individual. We are encouraged to date people who are in our own religion, but I know lots and lots of people who are mormons and have dated people of other faiths. I believe we are encouraged to date members for moral safety reasons, but I don't believe the church has ever come out with a hard and fast rule. You'll just have to ask. Good luck.

The guidelines for dating can be found in the For the Strength of Youth booklet (which is official church doctrine) Here's a link to that section: 
http://www.lds.org/library/display/0,4945,30-1-7-4,00.html 
It does not say that a member cannot date a non-member, but rather "Because dating is a preparation for marriage, date only those who have high standards, who respect your standards, and in whose company you can maintain the standards of the gospel of Jesus Christ." 
Of course, some members decide not to date non-members, but that's a personal choice. 
As for the other question here, the same document says "do not date until you are sixteen years old". I would imagine that one that followed that counsel would likely only date someone who was also 16 or older. But that would depend on their attitude: There's the "how bad can I be" attitude (who would), there's the "how good am I supposed to be" attitude (who might), and the "how good can I be" attitude, (who would not). 
At any rate, there are members who take the guidelines and commandments seriously, and there are those who do not. And whether they do or not says a lot about what kind of person they are. You probably want to be dating those who do take it seriously. They're the ones most worth dating.

You cannot date till your 16

There is this guy that goes to my school he is 13 and we have the same Beleifs just i am Christian and he s Mormon i Beleive in keeping virginity till after marriage and everything its just i really like him he is a very sweet guy he said he liked me to and he is very funny i am not sure what i should do.

I turned 16 6 months ago, i joined the church nearly 3 years ago so tehrefore i was dating before 16. I'm really interested with a guy at church, but my ex wants to be with me (i love him) but i know the boy at church shares my standards, but i find it hard to tell my ex. whar should i do?

if the mormon wanted to date befor 16 could they,all to their decision? and do the daiting things like holding hands,a few kisses here and there? cause most kids my age 13-14 date does he have to wait?

There are several factors which play into answering all of these questions, several more than have been mentioned. Yes, for Latter-day Saints the standard has been set for 16. Yes, we are counseled to date others with the same standards as us. Yes, the whole dating game is a difficult struggle and is played just a bit differently by every personality and upbringing. ALSO, keep in mind that there is no HAVE TO in choosing to be obedient. Part of God\'s wonderful plan for us, His children, is that He has given us this gift called \'agency\'. He has also given us each-other. In families, part of parents loving their children is helping them set boundaries. By following and staying within those boundaries, we are happier knowing that we are obedient. The same is true with our church guidelines. ALSO, a friend is supportive of another for who they are. So, if you know the one you want to date has a standard to not date until 16, that person would be more flattered that you respect them for that than to tempt them to change what makes them them. Great friendships can and ought to be developed, even if dating is not part of the package. At a young age between 13 and 16 friendships are more often better off without the formality of a date and the \'oh, I have to impress this person\' awkward thinking. Depending on the individual, some may even have no desire to date, whether LDS or not, until they are in their twenties. My advice, be their friend--you can learn a lot from each other.
