Does he care about me or not?

My ex boyfriend told me that he lied to himself about his feelings for me, that he never felt a connection with me and that he didn't miss me and admitted to not having valued my friendship. He told me most of this a year ago, and he told me again a few days ago after I confronted him for ghosting our friendship over a girl he just met. Although he says it wasn't for her and because he saw that this was going nowhere and I was being very distant, I told him some really bad things I regret and feel some remorse for and deleted him. I told him I still loved my ex because he valued me more than he ever did.

A few days ago I talked to his friend... I asked him didn't it hurt him to lose my friendship? Didn't he value me as a person? Because that had hurt me much more than when we broke up a year ago. He told me that he cared about me so much and always mentioned me and remembered me. And that he had always complained about how I was still talking to my ex boyfriend (after we broke up). I was completely shocked when I heard this, because like I said I was under the impression that he didn't care about me basically at all. If he didn't feel any connection why did he always remember me and why was he so jealous of my ex boyfriend (which I didn't know he was either). The reason I lost my feelings, grew distant and talked to my ex was because I thought he didn't care about me or showed any effort.

Now I don't know what to think. Did he care about me or not? Should I go talk to him? After hearing that I can't take it out of my mind and feel guilty for never having communicated our feelings with each other. I met someone on a dating app new to try to forget him (before I talked to his friend) but I just missed him more.

I know we were both very immature in dealing with everything, but I don't know... I began to feel guilty after some days but still thought it was best to leave the situation alone but when I talked to his friend, it made me feel worse because the reason we're in this situation now is only because we never talked about our feelings
