It’s been 30 days no contact

I’ve been fighting to not call him after going no contact for 30 days now. He ended things with me after nearly 2 years and after we broke up I’ve always been the one contacting him. He has said mean things post break up that hurts so much. We were each others first love and he made sure to let me know that I’m his first love but not his forever. He says we needed to break up because we are too different in lifestyle, communication style, and love languages. He seems so checked out already and never has he tried fighting for us/me. He even told me I can’t be the only one fighting. It hurts so much. We’ve done so much already together. Cared for each other when we got sick, consoled one another when we were having family issues, we have traveled together both locally and internationally. We’ve met each other‘s parents, and we’ve talked about a future together. None of that was enough to make him hold onto us ? Even in the discussion of contacting me post break up he says even when he has the urge, he’ll reach out to friends instead . And the chances of us healing and getting back in the future to him is unlikely . It hurts so much because he told me I was the love of his life. He said our love was unwavering. How could he be so cold now? Even tho he claims he’ll never, do you see a possibility of him reaching out? Is it not advisable to contact him after 30 days no contact because it’ll be me reaching out again? People say exes always reach out eventually is that true?I trusted him with all my heart. He was the last person who was suppose to hurt me. How could he be this cold even to someone he once loved. I don’t understand. I still love him and wish he’d change his mind.
