AITK for feeling hurt after my friend cut off contact during his placement prep?

I’m a 22F and I had a friendship with a guy I’ve known on and off since school. We reconnected again recently after a long gap. This time, he was in the middle of a very intense placement process, and I was in a gap year, studying from home and feeling quite isolated. We used to talk regularly, but mostly on his terms he decided the days and timing. I tried to be understanding of his stress and never demanded long calls, but I did emotionally rely on him more than I should have. I shared a lot about my fears, anxiety, and struggles, while he mostly listened and rarely shared anything personal from his side. One day, during an emotional moment from my end, I asked for a few minutes of conversation because I was anxious. He responded by saying he was extremely stressed with studies and “couldn’t afford one more stress.” Shortly after, he told me it would be better if we stopped talking for now and said we’d reconnect after his placement. He said it kindly and apologised but it felt sudden and final. Since then, there’s been no contact at all not even after his placement worked out. What hurts is not that he chose his career (I understand that completely) but that the cut-off felt abrupt and there was no check-in or closure afterward. It's been 3 months since he left and hasn't contacted me again . Even when I put a story he never sees it even though he likes and comments on others post. I'm heartbroken his last message was - I'll surely reconnect after this placement thing is over but it's been more than 2-3 weeks since he's been placed but he never bothered to come back .

Help me to move on please feeling so betrayed , devasted , heartbroken
