You posted do not say ILY. It greatly depends on how far along the spouse is in this jounrey. My H and I tell each all the time we love each other even though he is not living here.
He started saying it first, not me, so I am comfortable with that.
Don't send your spouse anything at this point in time. Keep it to yourself, work on your walk with God for now.
