Honestly LIfeline...I'm so worried about you. The way you and your H are going about this "reconciliation" seems to be more about him trying to beat you into the ground than reconciling.
But as for this topic, can you be a bit more specific about what the "thing" was that there is a disagreement over the "truth" about? You can change details to make it more generic if it is something painful. It would help though to know what type of thing you are speaking of...?
And one more thing...You only briefly mentioned in another post...that your H had a porn problem and possibly an EA online...can you please fill us in on that, a little bit? I think there is possibly something being overlooked here...
