Humiliated after rejection

Salam,

I felt interested in someone for the first time (like actually interested). I made dua that Allah would make it easy to talk to him, then out of thin air, i had a reason to. We spoke, he was super sweet and looked very happy, he was super engaged as well.

Few weeks later we spoke again, he was so uninterested and cut the conversation very short. I feel embarrassed, like he could tell i was interested and is trying to show me he doesn't want to talk. The feeling in my heart went away after that out of humiliation, but mentally i cant help but still be interested because of the things I know about him.

How can I handle this embarrassment? Should he no longer be an option?
