How can I tell if he is truly committed? I'm [25] and he's [27].

I'm a 25-year-old woman who just ended a relationship that wasn’t right for me about two weeks ago. Let's call my ex (Chris) — he doesn’t play a major role in this story, except that I met my current boyfriend while I was still dating him. A friend introduced me to a guy named Tony, who is 27. I made it clear from the start that I was in a relationship, so I stopped messaging him. A few days later, Tony reached out to ask if we were just going to stop talking. Eventually, I decided to break things off with Chris, who was abusive, thanks to my friend's encouragement to get away from him. Now that the background is out of the way, I want to share that I'm not someone who just goes with the flow; I prefer to know where things are headed and what people's intentions are. I communicated this to Tony during our first date, and we hit it off immediately; I really like him. It's surprising for me to develop these feelings so quickly. We've been spending nearly every night together. On our second date, while we were relaxing in bed, we talked about what we wanted in relationships. He expressed some nervousness about being in a new relationship since he wasn't quite sure what he wanted to do with his life. I reassured him that sometimes it's best to let life unfold naturally. However, his uncertainty made me anxious too; I didn’t want to invest in a relationship only for them to leave. When I asked him about his concerns regarding me, he said he had recently ended a relationship and didn’t want me to become overly attached after Chris. I completely understood where he was coming from and assured him that I just enjoy spending time with him. Tony asked if I was ready for a relationship, and I responded that no one is truly "ready" until the right person comes along and helps you feel that way. He said to let him know when I am ready, to which I pointed out that he's the one who's hesitant. Then, he asked me to be his girlfriend. I really like him, but I'm feeling nervous about how quickly things are progressing. I don’t want to get my hopes up based solely on the right questions being asked and the commitment being made. How did we go from discussing his reservations to him wanting to be in a relationship with me? Do men really know when they’ve found someone special?
