He’s battling low self-esteem

Sometimes, it’s not about you at all — it’s about how he sees himself. A man who feels unattractive, incapable, or uncertain in the relationship may shy away from closeness. His quietness at night may hide insecurities he can’t bring himself to confess.
He’s holding onto resentment
Anger rarely vanishes; it just changes shape. Maybe an old argument was never resolved, or he’s still hurt over something left unsaid. That bitterness builds invisible walls and his silence in bed might be how he protects himself from feeling vulnerable again.
He’s losing interest
This one hurts the most. When a man’s feelings fade, the first thing to disappear is usually touch. The tenderness becomes mechanical, the warmth disappears, and the distance between you at night reflects the distance growing in his heart.
