You are not interesting to him. Do not feed his pride. People are loved not for their skills and care for someone, but for the fact that they simply exist. If you have to make an effort alone, then this is already the wrong path.
But I understand your suffering. Once I also fell in love with a drug addict, and my soul was torn every day - even after she blocked me because I did not send her money for drugs.
In such cases, logic will not help you. Personally, that day, after I stroked this eternally sleeping cat, I went for a walk in the deep forest, right along the river. I decided to take off everything that was on me - and so I wandered naked, like a primitive man. At some point I thought: I have to run. And I ran - through a swamp, stones, bushes. Just ran. Surely, if someone had met me there, I would not have made the same effect on them as Forrest Gump. In the end, when I was exhausted, I realized that I had run to this beautiful place (picture 2). That's where I stopped. I took a bath and went home. At home, my father and I started making cutlets - here they are. At that moment, I was so tired that I thought more about food than about that girl. So the only advice I can give you is that you can try to do some strenuous physical exercise now. If you do nothing, there is literally a chance of getting a heart attack. You need to put your energy somewhere - and definitely not into your bursting heart.
