I need advice

I’ve known my best friend for 10 years, he is my next-door neighbor so we see each other every day. Our moms used to have a great relationship, but they are no longer speaking to each other due to the fact that his mother said some things to me about my family (while I was working at her store) that offended me and I thought that I should tell my mom because the were really close and I wanted her to know that she doesn’t appreciate us as much as we thought. I haven’t seen or talked to my best friend for months. A few weeks ago he saw my mother on the street and he was impolite. So, last week I saw him on the street an he didn’t bother to say hi, I texted him to tell him that he is way beyond contempt. Yesterday he replied to me that I was unfair and unethical towards people that helped me and that he does not consider me his friend anymore. In a few words, I told him that he shouldn’t have got involved in that because this has nothing to do with him and that I wasn’t unfair to anyone I just told the truth because they criticized and offended my family. I wanted my family to know who really appreciates us and I also do not consider him my friend anymore because he couldn’t keep my secret (he once asked me something about his cousin and he promised that he wouldn’t say anything, the next day his cousin texted me, and he never texts me or calls me or replies to my texts. So I assumed that my best friend betrayed me). Anyway, my best friend told me that he doesn’t know what happened with his mother (hard to believe because of his first message), that he stopped talking to me because I never suggested going out and for various other reasons. Moreover he said that he is willing to listen to what I have to say (I feel like he wants me to apologize for something), if I want to talk face to face I should text him otherwise we have nothing else to say and we we shouldn’t hang out anymore.

I really don’t know what to do, I know that if I meet him in person he will lie to me about the reason why he stopped talking to me. However I want to meet him because I really want to tell him off for calling me unethical, but I don’t like the fact that he suggests that I should text him to meet me, as if he doesn’t care at all! What do you say? Should I meet him?
