I think all of our cases are different. For instance. my H was sending 4-5 emails/day for more than 3 weeks, trying to get me to respond, so it wasn't intermittent contact or random text messages - it was constant attempts to get me to talk with him - but I was "going dark/dim" so I didn't really reply. I did the opposite of putting out feelers - I ignored several of his questions and made it clear with my sign offs that I wasn't intending to write back. I was always polite but only gave minimal responses to his attempts to start conversations, in spite of how persistent he was at trying.
Discovered OW1: 1/10, H refused to talk. H moved in w 1st OW: 3/10 H cheated on OW1: 12/10 H left OW1, moved in w OW2: 4/11 D: 9/11 Still miss H. Don't understand, H just left, never even talked w me.
