Feeling guilt over being upset about a short term relationship

I see so many people in here who were dumped after 2, 5, even 10+ years. I only dated him for 3 months and we were friends for a month or two before but I thought we were perfect for each other and that it would last. We got along great, our sense of humor was the same, we talked about deep things, sex was great, etc. I think I was close to saying I loved him. But he was bad at communicating, avoidant, anti committal and has religious issues holding him back. Out of nowhere he blindsided me and said he doesn’t feel romantically anymore (I think the “spark” from the honeymoon phase was dying out and he’s denying/suppressing how he feels). I’m crushed, but it feels silly to say given how short it was.
