I miss him but he dosent

Hi so this is my story, i loved this guy even when he had a gf , loved him even when he was heartbroken, loved him even when he made new gf and got heartbroken, then finally a day came when he realised my love and we came in relationship. We had the most beautiful and perfect relationship we were friends first so our relationship was fun, fiercy , loyal, no trust issues only love . Everything was fine until oneday he changed he stopped giving me time , stopped messaging me , i asked him whats the problem he told he he cant give commitments to me now because he has been dealing with his family problems, i told him it will he fine with time , if you need space tell me I will give yu that he said he is not sure of anything and brokeup with me. Its been two months since everyday i struggle to wakeup get out of bed i miss him so much i cant tell how much, its so difficult for me to moveon when i still love him and sometimes i find him so selfish to just forget our 5 years relationship in 1 day , i dont see any of his efforts of getting me back, but here i am struggling each day , i dont understand even god has not helped me they say god works in miraculous ways but i see nothing. I was loyal i was understanding but still he left me without reason, so yesterday texted him he replied me and it was cold so cold reply now tell me how am i suppse to moveon? I have tried walking reading writing painting travelling but everything remins me of him, i try to distract myself , i try to be happy but i constantly get reminded that the person i loved the most has left me and i have no reason to be happy. Idk what to do now pls help me guys pls
