Most Helpful Guy
How long was the time gap since he texted you? If it wasn't that long like under a day - just wait it out - pretty sure he had something suddenly pop up.
Pretty sure he is interested if he would do all that for you.
And you won't be seen as desperate - only if you reply right away or text him like after 2 min of him not replying thannn u seem desperate
Again just wait it out and try not to jump to conclusions - he might be caught up in something or you can text him first after a while if you dont wanna be seen as desperate
