Situation. You are shacked up and your man disregards your concern about marriage. He’s a no-action guy mated up with you. Or perhaps not even shacked up, just sexually active and you need to reach for the stars.
Suggestion. Buy an inexpensive or mock wedding band. Wear it all the time. When he or anyone else questions you about it, state only one of the claims below and perhaps alternate them. Never explain further or complain about him or anything. Just say one or the other without smiling; you can’t and don’t want to confuse your message with smiles:
“I’m embarrassed at what I am doing.” OR, “I feel to guilty about what I am doing.”
Then, quickly change the subject to minimize pressure for more info.
