Idk who needs to hear this but…my general advice, as a sporadic (likely fully ex) OLD user:
If you’re HV, you have some details in your profile pics/bio that show who you are- where you’ve been, where you go, what you love, what you do, what you believe in. These details give him something to work with, in terms of getting to know you as an actual person.
And if you met in person, surely there was some conversation, however brief, that would give him an inkling of who you are, or at least some memorable detail of your interaction.
In light of this, “Hi” and “Hey beautiful“, I’m sure you know is an instant unmatch/block. But I’m adding that any generic horseshit about how your day/week/weekend was, is, or will be (this excludes asking about something specific that was discussed prior that, again, relates to who you are) is also lazy and unacceptable as an opener. Unmatch/block. Men remember the details of sports stats going back decades, and the steps required to build or repair this or that piece of equipment. They can pick up on and later recall details, if they consider them important.
If he doesn’t do that when it comes to you, it’s because getting to know who you are is not important to him. That’s not how you want to start off. That’s the path towards the dreaded, dehumanizing relationship dynamic where he tunes you out, whenever you discuss details of your life that do not directly relate to his interests, akin to an appliance he wishes he could turn off when “it” is not communicating with respect to his personal tastes.
Being alone is better than finding your humanity rendered invisible by someone you love. Remember that the beginning is when he’s supposed to be on his best- if the best he can do is generic inquiries that spell out for you “I really don’t give a shit who you are”, it’s highly unlikely to improve.
