It’s a difficult situation, and still early days for you both. Keep doing what you’re doing, and I’m sure in time you can talk over some of this. I think it’s important to remember that although you perceive the lies as a way of dealing with panic, we have to keep in mind that other people might internalise that differently. None of us like to be lied too, and an acceptances of that will take your far. Sometimes it’s best to hold your hand up without putting a justification onto it.
Best of luck
