My post gonna be so late to tell share you what I’ve been thinking after read your post.
Well, this consider as he not interest in you. If a man truly love or like you, he will get time to text you even he is busy and say sorry or ask you how r u etc. But he didn’t. I think after he met with you because he want to make sure that you are his type or not, you both can get along with each other or not, so that why after meeting with you, he started to act something strange.
