Is there such thing as 2and chances?

I need some advice. I was dating a guy and at the beginning of this month, I noticed he wasn't all in the relationship. I confronted him about it and he confessed that he still has feelings for his ex. He realized he did when he found out that shes pregnant with another man's baby. We talked and he said he can't give me his all at the moment and it's not fair to me. He needs to heal and get over his ex and I agree 100% You can't give someone your all if you still have feelings for another person. So we broke up. The first week, we was still calling me at all hours of the day, like he usually did. I told him that I couldn't do that anymore because it was only hurting me more, not being able to be with him. He stopped calling. Anytime I posted anything on social media (just on my stories) he always had something back to say. I would respond and then he would and I would end it there. On Friday, he called me for the first time in a week. He said he missed me and he still had feelings for me and that he thought about me a lot and he missed out on an amazing woman. He told me that theres no one like me, that he will never find someone that is a ride or die (with questions <- inside joke 😅) He was a bit drunk so I know that's why he did it. I told him to take his time to heal. That I wasnt going to put my life on hold for him but if and when he was ready and I still wanted to be with him, that we could start over. He said he understood. After that day, he started texting me more and even sending me pictures of random things that reminded him of me. Monday and tuesday he even text me good morning and called me. The problem is I dont think he knows what he wants. Today I havent heard from him at all and I dont think I should text him nor call him first. Is he just keeping me around in case he cant find no one else? Could he genuinely have feelings for me and could it be that he really wants me in his life it's just bad timing? I'm not putting my life on hold but I cant stop thinking about him and I overthink a lot (I know, not good!) Thinking he has other girls lined up.

As I'm writing this, I received a notification of him reacting to a picture I posted with 😍😍

I look like a bum, I'm wearing leggings with an oversized shirt/sweater, fresh out the shower with no makeup. So that makes me smile hard but I know it shouldn't mean that much to me 😩
