If someone gets moody after a 3 years of relationship does that mean he doesnt want her or he is cheating?

Moodiness in a relationship can stem from various factors, such as stress, communication issues, or personal struggles. It is not necessarily an indication of not wanting the partner or cheating. It is important to have open and honest communication to address any concerns and understand the root cause of the moodiness. Trust and understanding are key in navigating such situations in a relationship.
