21.Criticism.
Everyone dislikes a bully, regarding gender. Imagine being nit-picked all the time by the one who is meant to love and accept you the most. People can only take being ripped apart and criticized for so long until their self-esteem is shattered. Criticism is one of them. As a result, this is a significant red signal in a marriage. That being said, no marriage could go smoothly without criticism. However, there is a difference between having a mature conversation that includes constructive criticism and nagging and demeaning.
Ask yourself how you feel if you are not sure which category your marriage belongs to. Is your partner making you feel stupid, overweight, dull, ugly, or insufficient in some way? You should be in the company of someone who encourages and motivates you to be the most refined version of yourself. What’s the point of being with someone who makes you miserable if you don’t want to be with them? You might be happy being single in that situation.
