Please help

My bf and i have been going through a lot and we recently came back together after a month long break due to his depression. He came back and was open with me and shared ti me how he was feeling and then we met this past Saturday to discuss everything. We got back together. I used to be co dependent and I finally got through that and worked on myself. I wanted to take things slow and we did but unfortunately I ended up sleeping with my boyfriend yesterday (tuesday) after just meeting him for the first time this past weekend. I know its natural and theres nothing wrong but im scared that I kind of ruined the “freshness” of what felt like a whole new relationship blooming again. Idk i feel very foolish and i feel scared that hes going to stop being the guy I just started talking to. I ended up talking to him and telling him i wanted to take it slowly and cried (even though ive been strong and havent cried jn a while over him). Before i cried and before i got into a serious conversation he mentioned how he didn’t think I was going to let it happen. But i did let the sex happen because I kind of honestly forgot about the boundary I had set. We have a cabin trip in two weeks and I just wanted to save it until then. I feel ridiculous kind of and it upsets me and scares me that I ruined this fresh new start by allowing the sex to happen with him. (We’ve been together for over two years at this point). Did i do something wrong or did I change anything? Is it possible to start fresh again and take it easy and still build a good relationship? I feel like im overthinking it because things did come naturally... :( idk i just love him so much and I want this to be healthier than it used to be. He deals with depression and im just idk. Im just scared things aren’t going to work out again.
