My F22 boyfriend M22 ignores me

We been together for over three and a half years. After every fight or argument he just dips and leaves me on seen sometimes for a week.. one time I said I will come get my stuff and then he texted “we should talk before ending things” he promised not to do it again.

Fast forward to now we were arguing because I thought we made plans to talk that night and I cancelled on my friends and turns out he was making plans with his. It made me feel like shit cause my friends were later busy with other people while I was waiting for my imaginary talk. (We are long distanced about 5 months of the year for Uni.) I was pissed and we argued and he left me on seen for the whole night. This made me feel like I didn’t matter and that what I am feeling is not valid and I felt crazy I am waiting for something anything while he is ignoring me cause it’s easier.

I ended it then. I didn’t want it to be over I still don’t. He didn’t even reply to that. We proceeded to argue more. Every time he just ends up ignoring me and showing no interest or care. I am just so shocked and disappointed and I feel like I can’t keep going anymore. It’s not like this in person. But the fact he isn’t willing to even text or call to try to sort things out kills me. I never expected it, it feels like he never or stopped loving me because three years to not even reply. I am going crazy.

Anyone can help? I love him I just want him to tell me the truth.

TL;DR: I left my boyfriend cause he ignores me and was never to reach out first to sort things out. I broke up with him and he didn’t even show an ounce of care.
