Either way, unlike the first type listed, he has probably had more positive than negative dating experiences overall, so he may be open right away or over time to a committed, authentic relationship.
He’s just not ready to involve himself in real-time dating with people he may connect with online.
There are a multitude of reasons why this happens, but at the core, he is not ready or able to embark in a substantive relationship, regardless of what his profile says.
(This category may also include the desire to act out sexual fantasies and fetishes that couldn’t previously be realized).
Interestingly, fantasy can be so powerful for him that when reality fails to compete, he finds ways to fade away.
When he needs connection or the fantasy of a relationship, he can effectively “order out” for a date.
