Will it ever stop hurting?

So this guy I really liked we broke up this past summer we went to high school together we reconnected 10 years later. We started dating. It's hard for me to just fall into something with someone and I wasn't expecting to fall him at ALL. It just happened and he liked me too. We were together 6 months. It wasn't perfect but when we were together things were good. We had 1 really awkward date and a couple days later when I called him up for a "Do-over" he tells me VIA TEXT MESSAGE that he'd started a relationship with someone else.... 🙄 it was the biggest slap in the face. I was hurt. I was embarrassed. There was nothing I could say or do but say "ok" "fine". Its been 6 months and just I just feel so stupid. And still so embarrassed about the whole thing. Looking back I feel like I should've known and never should've gone there with him from the jump. I just want... I want to not feel like this anymore. I want to be over it and I want it to go away.
