Bodies change. Illness, pregnancy, medication, surgery, a decade. What happens next in a couple is rarely the thing either of them feared, and it is almost never discussed directly, which is how a physical change becomes a relational one.
The usual sequence: the person whose body changed starts avoiding being seen — lights off, shirt on, deflecting the hand. Their partner reads the avoidance as loss of interest in them, because that is what withdrawal usually means, and pulls back to save face. Now there are two people declining, each concluding something about the other, and neither has said a word about it. Research on body image in couples has repeatedly found that the more powerful predictor of satisfaction is how a person feels about their own body, not how their partner feels about it — which is worth knowing, because it means the reassurance is landing on the wrong problem.
That is also why 'you look great' rarely helps. It is heard as kind and untrue, and it answers a question that was not being asked. The question was closer to: do you still want me, and am I allowed to be this in front of you. Compliments about appearance do not reach either of those. Specificity about wanting does — naming what you want to do rather than how they look is a different sentence entirely, and it is harder to dismiss as politeness.
The other half belongs to whoever changed, and it is one sentence: say the avoidance out loud. 'I'm not avoiding you, I'm avoiding being looked at' undoes months of misreading in about four seconds. It is a genuinely hard thing to say and there is no version of this that gets fixed while it stays unsaid, because your partner is currently working from the only available evidence, which is that you turn away.
If some part of this is you, say the one sentence this week: what you are actually avoiding. And if you are the partner, replace the next compliment about how they look with something specific about what you want.
