Hello, I am Rafael. Thanks for asking your question - I'm here to support you. (Information posted here is not private or confidential but public).
I am very sorry to know about this very sad and frustrating situation.
It's obvious you have felt very hurt by his words about what happened, and even more after not getting real understanding, empathy nor support once you confronted him about it.
Is this the first time in this six years that he becomes this mean? His behavior is abusive, since he has repeatedly been criticizing you in a very destructive way, which is obviously incompatible with basic respect adult people should offer to each other, even more when into a mature committed relationship.
Different people would feel and react in very unique ways to the same scenario, depending on how they feel, previous issues, personalities, resilience, how hopeful you feel about the relationship, other serious issues and more. Only you know how much this most recent issue could justify a break up, depending on how you fee, what you want and feel able and willing to afford about it.
Thank you for joining the chat.
You need to carefully assess the pros and cons in this relationships, and choose what you feel is the best for you. from your words it is obvious you feel so hurt by his wounding words that you feel you cannot trust somebody with such behavior any longer, and that he does not deserve your affection and commitment anymore. I do support your feelings and I think this reality requires time for you to carefully reflect on it and if you want to give him a new chance, but if he continues to show inability to even acknowledge how hurtful and destructive his behaviors have been, then I would support your decision to seriously consider a break up.
