How do I resist the temptation?

I live in a group setting with 10 other people in the same house (guys and girls). There's this one girl that I find myself really attracted to and we have such compatible personalities, she's constantly on my mind. I've gotten several hints that she is interested in me as well, and after drinking a bit the other night we kissed briefly. Now I can't get the taste off my lips and am having trouble controlling my willpower. However I cannot get into a relationship with her because of rules in place in the house. Any advice would be much appreciated!
