I miss him 🥺🙄🙄🙄

So, in the past I’ve talked to a co worker and I knew it was wrong. He wanted to stay to “friends” since we worked together, but yet he would show me and tell me different. I had to end things with him since I knew it was the right thing. We didn’t end on good terms because of me and I regret it. The thing now is I kinda miss our friendship although I told him to go to hell& to shove it up his ass. What should i do????🤦🏽‍♀️
