Davis also warns, "Boasting that he's 'not like others' could mean he holds himself in high regard and expects you to stroke his ego." Roberts suggests you strike up a conversation if you like the other aspects of his profile and ask him to describe himself.
This could be a sign that their last relationship ended recently, and he might not be as ready to move on as he thinks. Roberts says many online daters make the mistake of mentioning an ex or a trait they didn't like in a past relationship in their profile.
The red flag is multiple mentions and excessive details. Comparing himself to other guys multiple times in his profile could be a sign of low self-esteem, perhaps from a lack of dating luck.
