What does it mean when a guy says he doesn't like how things started off in the talking stage?

Guy kind of rejected me after we went out and he mentioned other stuff but he threw in that he didn't
like how things started off during the talking stage...
Was that just an excuse? Because if that's the case why didn't he just stop talking to me then…
I will admit that I was guarded and difficult due to past hurt and not being ready. I take accountability on that part
