Hope, I'm sorry to hear about this. I think you were right not to reveal your source - never do that - and also just to tell your H you know he isn't being honest about this.
It sounds as though contact continues with OP. What is the bottom line for you if that is the case? And what does this mean for your upcoming trip?
I can't remember if it has already been posted on your thread, but there is a suggested response to continuing evasiveness, dishonesty, lack of transparency...
I can only presume by your continuing lack of transparency that you are in contact with OP still. Or want the option of being in contact. That does not work for me. I can not feel safe in a marriage where my husband wants to continue contact with OP. So, here's what I'm going to do......(confirm what you are going to do....)
I think it is a case of being clear about your boundary here. And clear about how you will respond to your boundary being breached. It almost doesn't matter how your H responds. He may come up with excuses, but I think you already know that something is amiss...
