Well, the key here is, when you date someone, is that someone just an "object" to you, or a person? If you're only dating them to "even the playing field" with your wife, then said date has been objectified. Do be careful not to fall into that pitfall. Date someone only if you are truly interested in them as a person, without any "ulterior motives." It's only fair to the person you're dating.
Love means never having to say, "Put down that meat cleaver!"
