I need honest opinions

I need some honest advice because I’m genuinely confused about this situation.

I was friends with a guy for a couple of years but I originally ended things because he was getting attached and I didn’t feel attracted to him at the time. A few years later we reconnected and I decided to genuinely give it a chance. We ended up talking every single day for about 8 months, got serious, and even started discussing marriage.

He eventually broke up with me because of trust issues and because he felt like I wasn’t fully sure about my feelings for him. We went no contact for about 3 months, then he reached out again saying he had clarity and wanted to reconnect. Since then, things honestly seemed to be going really well. We were talking normally, and we even had a good phone call two nights ago and were planning on seeing each other.

Then the very next morning he suddenly removed me off social media and completely cut me off without any explanation. I contacted him from another phone because I just wanted closure and to understand what changed overnight. When we spoke, he mainly brought up old issues, said I don’t consider the things I say, and kept saying he was done, but I still never got a clear reason for why things suddenly ended again.

At this point I feel emotionally exhausted and honestly reached my limit trying to understand the situation. I’m posting this because I want outside perspectives and honest opinions since I feel too emotionally involved to see things clearly myself. I’m so lost
