Hi HM,
Even though it has been 2 weeks since you heard anything from him, there is a chance that he hasn’t forgotten you and will still contact you.
Indeed, he may be comfortable with being alone at this time.
However, at some point, he will want company.
This is most likely the time that he will reach out to you.
Thereby, it is best to maintain no contact.
You already know that his behavior towards you needs to change.
If you give in now and contact him because you miss him, he will get the impression that it is okay to keep acting the way he has.
Avoid posting pics on your social media just so that you can get his attention.
Just live your life to the fullest at this time as though you have moved on from him.
If he was truly fond of you, there is a chance that he will contact you at a point where he realizes that you are not giving in and that he also misses you.
