Should She Stay or Move On?

We met in college almost two years ago in 2022. After a few months of interaction, I proposed to him. He took his time, though he liked me at first, and our relationship flourished. There were no signs of cheating or disloyalty. After college, he moved to another city for work. Somehow, I feel like I was always suffering during placements, even though there was an equal amount of stress. I supported him in his darkest phases, but whenever he goes back to his hometown, he hardly communicates. In his day-to-day life, he hardly shows love or expresses his feelings, while I am head over heels for him. Our days usually start with a good morning and end with just a call, or sometimes no call at all. He has his friends and enjoys his time with them, but I feel no sense of appreciation, affection, or reassurance. I find myself constantly fighting over the mere issue of affection. I feel like I pour more into this relationship every time, even planning his future career more than mine. I sense that it's necessary to step back and look after my boundaries, but I feel no acceptance from his side. He doesn't seem to understand how much I'm affected, and even if he does, he does nothing about it. Here I am, getting madder by the day. My anger issues have worsened, while he shows no sense of affection. When I ask for a breakup, he says he will change for me, but nothing works. What should I do? I'm holding on to hope, and he does nothing.
