You're quite correct. We didn't recommend any wording. Our concern with it is, what is a dating relationship? If you went out on one date with someone, does that constitute a relationship? If you dated someone 10 years ago, is that a dating relationship?
Our concern was that it doesn't necessarily establish the trust relationship that we feel is integral to a spouse or a common-law. We did not consider alternate wording, but it is certainly something we can discuss.
