Oh my God I f*cked up

I told my boyfriend that I wanted to break up because he wasn't talking to me for the past 3 weeks and I thought he was ghosting me, but it turns out that his phone was broken, but he just replied "okay" to the message, indicating that he was fine with breaking up, but now I'm scared that we are officially over. A part of me just wants to forget it and move on, but another part of me wants to stay with him. I'm so pathetic.
