Is it improper (lack of tznius) for a husband and a wife to call each other: darling, sweety, cuddly, etc. in front of others? or is it only improper to touch each other in public? Or is that mutar also?
Thanks for your reply.
Answer:
In general, the special affection that characterizes the husband-wife relationship should not be displayed in public.
This certainly includes touching (in a manner that expresses affection). The question of using pet names depends a little on the society in question. In a society that is sensitive to such names, and reserves them for the level of husband-wife intimacy, they would not be appropriate for public use.
Best wishes.
