Remember that your senses are what you see, feel, hear, smell and taste. Don’t put your layer of interpretation on it. What did you see? I saw Y turn their back to me. That’s the fact. The interpretation is “Y is cutting me off” or “Y disapproves of me” which then sends you into alarm bells. Keep it to the facts. Say the facts. “You’re turning your back to me? Is something wrong?” Listen to what Y says. Trust that it’s the truth.
What I had to do was consider my partner’s character (what he said, what he did, just the facts) and decide once and for all if he was trustworthy. And if I deemed him trustworthy, that was my final decision. I acted “as though” he were trustworthy; I took him on his word and I took things at face value. I did not change this decision unless I had real evidence to the contrary. Real evidence. What did I see or hear. Not what did I think or imagine.
