Ending of relationship 18 UC, 1 UC, 47.2.3.4.6 > 53

I had an intense relationship which finished in a sudden way. He was giving very mixed signals the whole time. Since the beginning I felt like walking on eggshells. He would send some surprisingly nice messages that he wanted to see me and he appreciated me, and at the same time not really making time to meet. He said he was very busy with work. I thought he was just taking it slow and just accepted it but one day I was so fed up that I wrote him a message saying that I feel he has no interest and I can’t continue this way. He said that he understands and he is not planning to have a long term relationship with me although he was attracted to me and he really appreciates me. He suggested we could meet up to for coffee a last time and talk about what was not said… I took it as a generous and kind of normal gesture, my intention was not breaking up by message but he was so busy that he had no time to meet.
Nearly 3 months passed since and I feel still stuck with this issue. I accept that he is not interested, but I feel hurt that he had no time not even to talk once. A month ago I wrote him and he said he was still busy and we will talk “later”. I know he is meeting his friends and he is active on the dating site so it’s just that he can’t be bothered.

I feel really down with this. It’s never happened to me that somebody I had intimacy with has no time and interest for a last coffee to talk, or a phone call at least. He used to talk about this fantastic connection we have etc. My mind is all the time around this.

I asked: Why I lost so much my self-esteem because of this? Hexagram 18 unchanging
Then: What can I do to close this issue in me and get over? Hexagram 1 unchanging
Last question: Can I do something practical towards him (as write him or explain my feelings etc): Hexagram 47.2.3.4.6 > 53

My conclusion:
18: I have to work on my self-esteem in general.
1: Some creative attitude in general in my life can lift me up and I can get over this experience.
47.2.3.4.6 > 53: I don’t understand it. I asked this question but in fact I am very afraid to expose myself to another rejection, and although I think it’s painful to cut contact in a radical way, I have to accept his needs. And just no contact.

Thanks to anybody who can interpret or give an advice.
