Chased my ex. What should I do?

My ex and I dated awhile ago for 3 years. We broke up cause I was away for university, but we’ve had periods of no contact and then someone would reach out and we always come back to one another. This time I feel like I made myself look kinda crazy lol. I kinda got annoyed at him when he randomly didn’t message me one day, and when I texted him again, he said he wasn’t in the mood to speak to anyone. We both suck at texting to begin with so this just makes things worse. Currently I’m in medical school and he works so it makes communicating worse. I feel like I was chasing him when I message him again after he wouldn’t respond, partly because I also wanted to make sure he was doing okay (from past experience). Regardless I feel like I chased him and I don’t feel too good about that. We haven’t talked for 2ish weeks now and I’m currently not even in the same city as him as I would only be back by Christmas. Obviously, I want him to reach out to me but did I make myself look kinda pushy? Is there anything I should do now?
