Cover art for Desire lyrics by Winery Dogs, The

This is about a guy who really likes, and still has feelings for, a girl that he used to be in a relationship with. When they broke up, he felt like she really screwed him over and he was hurt pretty bad by her actions. Now, after all their history, she is coming around again and making advances. He wants her and desires her in a physical nature, and wants to reciprocate her advances, but he holds himself back because he can't forget and get past how bad she treated him before.
The last line is supposed to read "though I want you so, I don't think that I can let go." This is a great song!
