Context: Jery is in love with Bätely, and has been courting her for a year. She is all cold-shoulder, and after he again tries to win her heart as they banter with each other, leaves the conversation, and goes on her way back to her father's farm. Jery then says:

"Gehe, verschmähe die Treue. Die Reue kommt nach!"

So the reading is simply one of him being frustrated, his faithful and unrelenting pursuit of her having been scorned once again, and he prophesies that she will regret not having warmed to him (or to any other suitor, apparently; propheticallly, I feel, the next scene is Jery talking with an old acquaintance of his, who is now a dashing soldier, and something of a womanizer. I haven't read beyond that, but I can sort of feel an inevitable development to the story ;)

But I'm afraid that context - as usual - makes the quote that much less interesting ;)
