Speak politely.

If you cherish this friend, you can say what you think and ask him why he has treated you like this recently, which shows that you don't like getting along like this. Compromise will only make the problem more complicated. Only by knowing what the other person thinks, finding out the reason why it is so bad for you, solving it and making it clear, will you naturally return to your previous relationship, or even better! If you feel too tired to keep this friend, try to alienate him. Perhaps, at some point, he will realize his wrong way and take the initiative to contact you and make up. The days are still long, and the future can be expected. I believe you deserve better!
