29M got dumped by my GF 28F but for some reason during and after the break up, I couldn’t cry at all. Is something up with me?

Hello! I got dumped around march and before it ended I could tell that something was up. I was avoided for about two weeks and couldn’t get the proper communication till everything ended. Then saw that she was basically with someone else about a week after it all ended. During and after the break up, I couldn’t cry but I have this overwhelming feeling in me that I can’t do anything about. I’m not sure what to do. I’m in the gym, I started taking dance classes, and got back in school. My confidence is kinda back to where it used to be and I’m doing the things that I love again after giving up on myself during the relationship. But for some reason I feel like crying sometimes but it won’t come out. I miss her dearly but I know I’ll never get back with her, but I don’t know why I’m feeling like this. Has anyone ever gone through this kind of feeling? If so, how’d you handle it?
