I am in a relationship, it is about to be 2 years and everything so fine, our love, care for each other, the way we give each other preference everything seems perfect but once in a month almost every month, there is a trigger point, a harsh conversation would heat up on any stupid topic and it will end up in toxicity like not talking at all, blaming each other, finding each other's fault and picking up all past conversation and what not. Even after it get sorted we talk about it that how we should deal in that kind of situation, everything. But nothing worked out till now. Everytime it is one thing or another. And this happened again 3 days back. We are not communicating. I am not able to talk because the things is said to me is hurtful and he feels he didn't do anything wrong. I don't know what to do.
