How should I handle this situation?

I dated him before, but we broke up. Recently, it seemed like we were getting back together. On Monday, after returning from my trip, we met up, and we were intimate. Afterward, I asked him, “Last time, when you said, ‘When you come back, let’s be together,’ did you mean together in a relationship?”

He responded, “I don’t remember saying that. I think I meant let’s get together.”

Hearing that, I felt really hurt and started crying in front of him. He told me I was being too emotional and said, “You’re making it seem like it’s my fault, but actually, it’s because you’re not strong enough.” He also said I needed to face some challenges and suggested that I see a counselor.

I quickly left his apartment. Before I left, he tried to hug me, but I refused. He said, “You can’t even give me a hug?” A minute after I left, for some reason, I went back and hugged him. He looked impatient and said, “Chill, relax.”

The next day, he texted me: “Hi. Are you okay? I hope you’re having a good morning.”

I didn’t know how to respond, so I didn’t reply. It’s been almost a week now. He hasn’t reached out since, and I just saw that he updated his Instagram. Does this mean he really doesn’t care about me? If someone truly cares, they wouldn’t just send one message after seeing you cry, right? I feel so lost, like everything between us doesn’t even seem to have affected him. It feels like the only one hurting here is me. Do I still need to respond? Or should I just leave it? How should I handle this situation?
