I feel stuck, abandoned & discarded.

My now ex boyfriend ended our relationship a month ago two weeks into our break up he texted me saying he's going to date someone else, then blocked me before I could respond. His daughter told me earlier that day( while he was at work ) about their weekend plans with his new girlfriend. I didn't reach out to him. His text was more for damage control, I believe. Since then I was doing ok coping with it but this week he had his birthday and I had purchased back in January some tickets to see Fluffy as an early birthday present. I ended up going on my own. It was brutal and broke down. I don't know how to move forward, I feel stuck and abandoned. I wish I could move on as quickly as he did.. I feel so alone and a big void .💔💔💔
