Cant get past him leaving

Hello everyone. I was recently dumped. My boyfriend walked out on me oh January 7th, we had plans he said he had to get his friend at 8pm. This is 4:40pm I just got home from work. So I told him if I was now on a time limit and why he couldn’t tell his friend he had plans already. Then I asked where I stood in his life and if I was even a priority. He then sat down looked at my beta fish and said “I wish I was free like this fish”. He then said “ in hot I’m going to get some air”. I said “you been standing in your jacket why don’t you just take it off”. He said I still need air. I said ok. I waited and waited. He wasn’t coming back...I went to look and he’s gone!! Took off in his car. I called no answer. I called again he answered said needs to think. Ok. I left it asked if he’s coming back tonight he said yes and we’ll talk when he comes back. Long story short...kept saying he’s coming back and will meet me kept putting it off and off. Then January 13th I txt him and asked “are we done”. He answered “yes”. After that all I txt was to come sign the insurance papers. Kept putting me off. Then as of Friday the 15th I have heard nothing. I stopped texting him as of that day as well. He just took off on me, no explanation and no reason, wouldn’t meet me so we can talk. Not even reconcile. I just wanted to know why. Now I’m left here crying since the day he left. Since the 13th I been crying everyday cuz that’s the day that made it official. I miss him so so much I love him and can’t get him out of my mind. He doesn’t even care to get in touch while I’m hurting so bad after he just dropped me like a piece of trash.
