A wife who is not happy at home does not necessarily express it through anger and confrontation. In most instances, it presents itself silently as a behavioral change, withdrawal of emotions, or some minor changes in day-to-day routines. They tend not to be done to punish or distance but to help deal with the feeling of being unheard, unappreciated, or emotionally drained. The knowledge of these signs can be used to deal with problems before they become more profound.
They grow emotionally silent

A dissatisfied wife can cease to show her emotions. She might find that there is no longer any understanding in sharing, so she is safer in silence.
They stop arguing

Disappearance of the arguments is not necessarily a good omen when it happens. It can be that she has lost faith in her voice, as it will not make a difference anymore.
They spend more time alone

Solitude is a choice that is made to restore emotional energy. Staying alone may not be as exhausting as attending a place that may be stressful or unfriendly.
They pay greater attention to distractions

Coping tools can be in the form of scrolling on the phone, watching TV, or keeping busy. The distractions are useful in preventing emotional distress at home.
They get easily frustrated

Minor problems can have a tremendous response since frustration has been accumulating over time. The frustration is usually regarding the internal feelings that remain unresolved.
They seem constantly tired

Emotional pressure has a physical impact. She might be exhausted and not motivated, even with sufficient sleep.
They avoid deep discussions

Heavy debates can be tiresome or meaningless. It may be a strategy of avoiding disappointment or conflict.
They stop sharing their day

She stops discussing the day-to-day experiences, which is why it is likely that she is not emotionally interested. It is through sharing that one feels unappreciated.
They seek validation

The compliments or the nice words of others can be soothing. This does not necessarily imply betrayal, but a desire to be visible and noticed.
They grow up and get more independent

Dealing with the duties on your own may be empowering and protective. Reliance can be substituted with independence in case of a loss of trust in support.
