Does this mean he is not interested anymore ?

Okay, so i have one so called male friend from high school, he liked me at the beginning, i know this, he was very attentive to me, told me many compliments, asked me out etc... but I avoided because he was crush of my bff and I knew that from the beginning. But now she doesn’t like him anymore and i am free to have relationship with him but there’s a problem...

The last time he asked me out i acted silly and didn’t go out that day... then he messaged me , asked me reason, he seemed to be very angry when I tried to explain i just received seen... thats it ... it was 2/3 months ago... no more messages from him since that... 1 week ago i met him accidentally outside with my friend we spent good time together but after our hangout no messages from him... it is first time when he didn’t message me after hangout i am very upset... instead he messages my bff. He was never interested in her that way before... I don’t know what to think about it... he still likes my pics on social media but it doesn’t matter not a big deal... what do u think girls about all this situation? Does this mean he is no longer interested in me?
