We are not officially dating yet
To a guy, calling a woman his girlfriend is typically a huge pain in the ass and if the woman is making herself so available and so committed when he hasn’t committed to anything, why would he call her his girlfriend?
Moreover, usually the women giving “advice” are single and haven’t had a successful relationship to date.
Maybe he likes you, but he doesn’t want to feel “tied down” by a relationship.
Maybe he likes you a lot, but he knows that he’s not in a position where he can fully commit to you because he has a lot on his plate to deal with and will continue to for the foreseeable future. Regardless of the reason, it’s nobody’s job to play psychiatrist or detective.
The relationship at the moment is either working for you or it’s not.
I think there are a few traps in this sort of situation.
