Is it possible to love your best friend in a non romantic way?

I’m a little confused by relationships in my 20s, from the age of 18 to 21 I had a best friend who I would spend a lot of time with, care about so deeply, want to talk to her all day every day.

Looking back, I think I loved her,but not in a Romantic or sexual way. I thought she was beautiful though.

We lost touch as we moved away and our relationship became distant.

I’m now 27, and have never had that with anyone else. I date people and try and make friends but everything stays such surface level.

With my ex boyfriend, I thought I was connecting with him on that level in the beginning, it certainly felt that way. I started to care about him deeply, talking to him all the time, sharing vulnerability. If he was sad I was sad, I wanted him to be happy, I missed him all the time but 3 months into our relationship, i realised he was distant, low effort, we didn’t connect deeply anymore and I lost feelings.

It’s been a. Year and now I’m worried I’m incapable of love or feelings and scared I’ll never have that.
