I think it is important to be upfront. At some point, if the relationship progresses, I favor a thorough disclosure. There seems to be wicans with any number of beliefs. Are you a solitary wican or a member of a coven? If there are children, will you insist they become wicans?

What wicans believe encompasses a wide divergence from Christianity and other major religions. If the relationship gets serious, I think fairness dictates more than vagueness.

Be well.
