Do I consider the relationship as over? (19F) and (25M)

So..I’ve been dating this guy long distance since July. I’d say it’s a relationship where I’ve flourished a lot thanks to his support and love to me. I’ve told him things I’ve never told anyone, and I’ve shown him things I’ve never showed anyone. He’s definitely been my first in a lot of things, so he means so much to me. He helped me realise that I have every right to be confident in myself, and I enjoyed having someone to always go to and be there for me.

This is where the problem comes though..he works a corporate job and is always busy with work. Last week Wednesday he didn’t text me until Saturday and went completely silent on me, and it turned out one his family members had a minor accident. I genuinely thought I had been ghosted during that time so I felt so hurt, but when he finally did reply he told me he doesn’t care about anything right now, that I can be mad at him and he’ll figure it out later, that he would give me an apology but his heart’s not in the right place to and he doesn’t want to give an ungenuine one. Fast forward to today, still no messages since that day on Saturday. I’ve been through a lot since then, I’ve cried for hours everyday wondering why he wont text, surely he can’t be THAT busy? And if something is wrong, why won’t he let me be there for him and support him? What do I do? I’m worried he might not reply again but the texts are all going through, just unopened (Whatsapp).

I have never felt so hurt in my life, but I still wish this would all work out.
