Is it normal if my ex and i can talk about anything?

This is what happens to good people and I believe I have good judgement and luckily, I came across someone with the same common sense and humbleness. Although things didn't end well between me and my ex, we remain good friends and still enjoy each other's company. Yes it took a while to recover especially for him because I was the one to break up with him but we slowly put that nonsense of "no exes can't be friends" and saw what was in front of us and realized we were proving everyone wrong; we're being friends right now so why can't we? cause society says its impossible? Fuck that. It's rare but it wouldn't be rare if people stopped thinking too much and just lived. Anything is possible. I just recently told my ex in person, who loved me, and looked at his eyes, and told him about the current guy I've been dating. I told him "I love him" and almost teared up and he said "ya I can see it in your eyes." He had asked what do I think about him, how I feel about him after discussing relationship stuff. And we just giggled it off without being so awkward about it. He was sucha good friend about it. I even straight up asked him was that torture for you to hear? And he was honest and said "it could be awkward but its not actually." Idk if we're just kool people like that or I should be so grateful to be who I am and to have met someone like him, someone else with the same mindset as me. People can be so brainwashed and stubborn that they make everything ten times more complicated and impossible.
