Straight guy retracted back everything he said

I had this “situationship” for years. Just yesterday, we talked in his car about everything, since we had a major fight that we never talked about until then. I was so heartbroken when he retracted back everything he said to me then, in a sense that he was confusing me that it was just me the whole time; his reasons were fabricated and did not match what actually happened at all during our good/bad times together. I am just confused because saying “I love you,” holding my hand in the haunted house, sending me selfies of him without glasses after I started complimenting him that he looks better without glasses, and saying “If I have a power, I would turn [my name] into a girl.” Is this something you’d say to a guy friend, especially we’re never really like “bro” or “buddies” together? And now, we’re over, we’re done. I asked if he wanted to be friends again, but he said not now. I am not doing mentally okay after that. Intimate bonds and moment could be harrowing in retrospect, and that is true in my case.
