I like him so much, but why he is not texting back, or what do you think of this situation?

I think you are worrying for no reason, he likes you, he has asked to see you again. If he wants to pay, let him, he wants to make you feel special. Graciously accept and thank him. Try to calm down and dont worry about what you do, he is probably as nervous as you. You also need to learn to spell better!!!! Good luck
