Tam,

No matter how you answer, wait 24 to 48 hours before you do.

Some MLCers want the spouse to be seeing someone as it relieves their guilt about the affair.

You know your H the best. If you think he's asking you out of jealousy if you're seeing someone I would use this opportunity to set a boundary. I would tell my H that I do not ask about your personal life, please do not ask about mine. I would state it kindly, but firmly.
