Hello dear!
From my experience DO NOT TEXT FIRST, let him reach out to you. And when he does it, be nice but give him dry answers, also give him the cold shoulder.
If he senses that he is losing you, he will chase, promise. Also do not talk a lot with him and say you are more of a “talking face to face person” and if he is interested he will ask you out to go on a date, I SWEAR!
