Dilemma.

So, I put out this commitment to myself that I wouldn't date until I completed the spiritual class I signed up for. I thought it was a year class, but it lasts until October 2012! So now, what do I do? Can I keep that commitment? Can I go like almost two years without sex!? (And I am ONLY doing the sex thing within a relationship, so no cheating on that. My heart gets too involved, even if I try not to let it.).
