What Are Your Thoughts On This Ladies

I was with my ex boyfriend for 7 years. I never had a real relationship so meeting this person I thought we were going to be together for a long time. I took our relationship very serious. I never cheated on him. I stood by his side when he was getting his life in order. Watched him share tears, giving him advice and been there for him when he wanted to give up on life. Fast forward, 2018 my whole life have changed when I had found out he been cheating on me with another girl throughout our relationship. She reached out too me on facebook and told me about their relationship. How did she found out about me because he kept old birthday cards and gifts that I have giving him. (Him and I wasn't living together) and on top of that she tells me they've a child together and brought a home together. I never knew what pain felt like until I experience this. Once his secret was expose and everything came out in the open. I made that decision to end our relationship. All I every wanted was him to admit what he did and apologize to me but I never gotten that apology. However, he apologize to the young lady he was cheating on me with and blocked me on facebook. It took me 4 years to heal from this pain and to move on with my life. Now, here it is 2023 and I get on facebook to delete old post on my profile. I happen to see a old post of us and a comment he wrote. I happen to click on his name and see that he unblocked me on facebook. He kept me in the block for 4 years after our breakup. Now I'm wondering, Why would he unblock me outta all these years? Does he want me to know that he unblocked me so I can say something too him? Or....Is this is way of thinking about reaching out too me?.....What advice would you ladies give too me.
