my sp found someone else

I’ve been trying to persist in this for a while. We had a good connection but he had weird patterns I was trying to remove. I called today and he confesses to me he was seeing someone else seriously and I don’t know what to do or how to feel. I genuinely feel like this is end game and I was excited but now I just feel a bit disdain yes upset but also idk how to keep persisting or feeling good about saturation anymore.
