Potential Cheater? Confused….

This isn’t a you problem, but it also may not be a problem at all. Does he have any history of looking to other women for validation, in your relationship or in his past relationships? Has he ever cheated on anyone? Do his insecurities ever make him mistreat you through disrespect, tearing you down, making you feel less to make himself feel better? If the answer to all of these is no, and he generally is a decent person, I don’t think I’d worry about it unless he starts doing any of those things.

If he feels that insecure and bad about himself, he may find it helpful to talk to a therapist. But that’s up to him, you can’t force him to deal with his own issues if he doesn’t want to. It is something to consider prior to getting married if any of his personal issues are negatively impacting the relationship, though.
