First of all, it is problematic for this married man to frequently log on to jiayuan dating websites.

However, as long as he doesn't post his marriage information on the dating website, or has a good relationship with the little girl on the platform on the grounds of unmarried, then he is not cheating. At best, it's an affair.

As a married man, being loyal to his family, his wife and children, love and his family, as well as the bad habit of browsing marriage websites, really makes his wife very uneasy. It may cause misunderstanding, quarrel and destroy harmonious family relations.

The above is my opinion, for reference only.

I hope my answer can help you and make you satisfied.

Finally, I wish you a happy life and a happy family
