I think I fucked up a good thing.. help.

Guys, I think I’ve finally met the guy that I’ve always wanted before I met my ex. Loyal, honest, straight forward, funny, caring, etc. All the things I could’ve asked for and I hate myself right now because I fucked it up. We got into a conversation and I mentioned to him who’ve I slept with in the past. I left out one of the guys I use to mess with because that was a mistake. I left that out because I felt like he was going to judge me (and maybe not but because of past experiences with my ex I felt like he was) and be quick to leave because he might have thought I was easy or a hoe or something that’ll turn him off and make him walk away. I didn’t want that past mistake to define the person I am today. The person I am right now. So I left it out and lied. He ended up asking me about the person I left out (idk how he even found out I use to talk to that person) but he asked if we did something and I wanted to be honest about it and said yes. He got so mad to the point that he doesn’t think things will work out. I haven’t lied to him before. This Is the first and last time it’s happened and ever going to happen. I just wish I was up front and not scared to be honest about it. Now I’m trying to fix things. I know trust is hard to regain but what can I do to fix this? I want him in my life and I want to do anything and everything to fix this! Don’t know whether I should just give up and let it be or keep on talking to him and see if he wants to work this out. Anything would help!
