This is what happened to me.....(happy ending)
dated a non-member for two years. Amazing guy, basically followed the word of wisdom already and very spiritual. He wanted to take the missionary discussions because he was looking for more in his life, looking for truth. He also knew I only wanted to get married in the temple and would not compromise.
He investigated for about a year, refusing to get baptized until he knew it was the right thing to do. Finally, he received and answer to his prayer and he was baptized. (the Lord always knows the right timing for things, trust in him) Then we waited another year to get married in the temple, in that time he became a worthy Melchizedek priesthood holder and we got to plan a beautiful wedding in the temple and a small ring ceremony for his family and most of mine. It all turned out perfectly.
I suggest waiting for the temple, it is worth every second. plus, once you're married you'll forget about all the time you had to wait, it goes by fast when you're planning a wedding!
BUT i agree with people above, IF you do have problems with chastity, then get married sooner rather than later. We had some problems early on and had to go through a whole huge repentance process and was very difficult (the guilt eats you alive)....so....either way WAIT TILL HE'S BAPTIZED. :)
