Quote: "Is that still considered wrong? "
The question would be considered wrong by whom? God, observers, his wife, or those who hear about it (I don't mention the man and woman in question since they seem to believe it is fine.)
God would examine their hearts, and he truly would know if this is all in innocent fun. Observers are going to be making their decisions about this being wrong or right based on their own life experiences, and how well they know these two people and what they believe the motives are. His wife will make her decisions in much the same fashion as observers, adding her emotions, hopefully Christian counsel, and that she knows her husband's heart better than an observer (hopefully). And, those of us who just hear about it have only to go on very limited information, and the what the bible says about it.
Wrong or not---it is not a very wise idea. After "is this Godly or wrong", the next part of the decision process should be--"is this idea wise and/or beneficial?"
I would discourage this behavior because the man is "possibly" looking for female attention (innocent or not) since he has separated from his wife. This can easily lead to places that are not Godly.
