How can I manifest reconnection with someone I still feel a strong bond with after a breakup

I was with a man for four months. We were both very affectionate and had a good understanding of each other. We carried pain from our pasts, but we talked a lot about it, and I felt a genuine connection. However, there were some differences between us, and we started discussing breaking up. He ended the relationship, and I had an emotional breakdown, which led him to block me everywhere. It’s been over a week. I still feel we have a connection, and I sense he’s angry with my behavior. How can I practice manifestation to align my energy with him, or at least open a line of communication?
