Neither. Her text is asking for your vision. "So if i ever did decided to come back in the marriage what would that look like/entale?"
Her text is an example of indirect communication. She is communicating information without being responsible for the information she is communicating.
As a man, you have probably done this type of communication a dozen times and not realized it.
For example, when you were a teenager you probably asked a girl, "If I asked you out on a date would you say yes?"
If the girl said, "Yes, I will go out with you" then you could ask her out without fear of rejection. But if she said, "No, I'm busy" then you could drop it without being rejected.
When your wife engages in this type of communication just accept as it is and don't analyze. As your relationship grows more intimate so will trust in communicating.
