Trying hard not to contact him

A couple weeks ago, my (30F) LDR boyfriend (31M) of a month ghosted me. He ignored me for days, following him snapping/cussing at me over text, the last I heard from him was him replying when he was off of work, saying he’s tired.

After not hearing from him for days, I did what I had to do and dumped him. He still hasn’t contacted me since. I haven’t contacted him either.

I am so filled with pain, rage, disappointment, and resentment. He treated me so well and I thought things were going great up until he got upset with me for the first time those two weeks ago.

I’m trying so hard not to message him and go off on him and tell him how I feel. But I know that won’t fix anything or get him back. I need to stay strong and remain no contact, but it’s just so hard and I’m hurting so much.
