Texting is safe. Calling you and asking you out isn’t. Right now he’s enjoying the connection, the attention, and the flirtiness without taking a risk. That doesn’t mean he’s a bad guy, but it does mean he’s comfortable where things are.
You don’t need to play games or ignore him. And you don’t need to pressure him either. You can be clear. Something simple, like saying you enjoy talking to him but you’re not really looking for a texting friendship. That opens the door without pushing him through it.
If he wants more, he’ll step up. If he doesn’t, you’ll finally know. And honestly, clarity feels way better than guessing.
