Will he realise that he has lost out on a good girl? If not now, months or years down the line?

We were due to marry in 2 months. Honestly, I wasn't happy but I didn't have the courage 2 call it off. We were 2geva only 8 months & it was a long distance rship. Our good times lasted first 3 months. I wanted more time in getting 2 kno him but he was adamant on marrying asap & settling down. I agreed. As time went, I realised he had no respect 4 me, arguments became frequent & he resorted 2 calling me derogatory names each time. Names included "retard", "imbecile." I explained how I felt but he would say "I have to call u names because I can't hit a girl; Name calling isn't personal 2 me; ur over sensitive." Many occasions, he demanded a break. He even used to check out other girls in front of me. He wanted me 2 become more modest with my clothing even tho I don't wear revealing clothes. The last few weeks of our break up became really bad. I put him first in absolutely everything, gave him so much, recreated his CV, made lots of effort 2 c him. He was so ungrateful. During this time I was realising he wasn't ready 4 commitment as his decisions didn't consider me. I wasn't goin 2 get a proper honeymoon bcoz of his messy finances but he was goin abroad 4 a stag. We decided a break for 2 wks & 2 days in I created an Instagram a/c. I went 2 follow him, I saw that he had liked a girl's pic who was wearing next 2 nothing. I felt so hurt. Hypocrite. Next, I made a mistake which I feel so disappointed in myself 4. He'd told me something in confidence & in anger, I exposed this secret to his dad. Since then, he has blocked me on whatsapp & doesn't want anything 2 do with me. I've told him countless times I'm sorry, but he doesn't want me. I've been texting him quite a lot with abuse & he said I was harrassing him & ignored me after. 1 month down the line, I see that he's enjoying life & been on holiday.
But my only question: will he realise what he has lost in me? He'd told me on the day I returned his belongings 2 him that other than the mistake I'd made, I was perfect.
