Cool so I was right, woohoo! I haven't been in that situation (and will make sure that I won't be either!). I just put myself in their shoes and that's the only explanation I could think of.

Treysdad, there's a difference between the guy realizing that the relationship isn't as "sweet" as he thought and him going into the relationship with the intention of "getting her". If she didn't turn out to be "the sweet fruit" he thought she was, then breaking it off is fine. But if he's dating her just for sake of getting her to fall in love with him and then leave her then that's definitely not ok!
