This doesn’t sound particularly promising.
However, being that he was the one who initially pursued you, there may be a small degree of genuine interest that exists.
You should avoid initiating contact or reaching out, just as you have been doing so far.
This allows you to maintain a degree of strength so that you avoid coming off as needy or desperate.
To steer this in a good direction, start engaging in activities that you know that he is interested in.
Post pictures of yourself engaged in those activities on your social media.
Look like you’re having a good time.
The idea is that whenever he looks at your social media, you will be showing him what you have in common with him and how much fun he could be having with you if he were to engage in those activities with you.
Doing this may build a degree of desire in him that causes him to reach out to you.
