schedule conflict

My boyfriend of six months unexpectedly ended our relationship, citing our incompatible schedules as the reason. He claimed he still wanted to be with me and genuinely cared for me, but we were only able to see each other every three weeks. He felt overwhelmed by work and other commitments and believed he couldn't give me the attention and love I deserved. When he initially brought up the issue, he asked for my thoughts, but during our call, it seemed he had already made up his mind. We didn’t agree on a no-contact period, but that’s how it’s turned out in the days since. I’m trying to move on, but I had strong feelings for him. Though I’m aware I shouldn’t hold onto hope, part of me can’t help but do so.
