My view is the same as before.

He isn’t interested in being romantic or friendly with you, same as before.

Him isolating and not going places doesn’t mean he is interested in talking with you. It’s his choice to not hang out. Who knows what he is doing. He might have new friends and cut ties with old crew or is busy with other stuff or just wants space.

Same as before I urge you to leave the guy alone. He isn’t responding to your texts and hangs up when you call because he let you know several times he isn’t interested, not because he is upset

Your other friend meddling for who knows what reason.

I recommend you talk to a therapist and try to break this pattern of pursuing this person before it becomes a serious issue. He told you to stop contacting him, to continue it could cause legal problems.
