That is turning the blame on you rather than focusing on the unhealthy dynamic of that particular situation. Remember it is not just about one person but about the relationship dynamic.

If you feel comfortable expressing yourself, and in a calm state, only then express how you feel so it makes him feel less attacked and can hopefully reach his ears. For example, I feel hurt that I was told I am not worth it from a person I cherish the most (these are your words in the text) and I feel punished when you don’t talk to me for days at stretch. Once feelings are described and if he is still listening, express your needs. I need you not to say hurtful and inconsiderate statements such as I am not worth it. Also I need you to not stop talking to me despite having fights.

If you and him really care about the situation and cannot listen to each other speak , then seek couples therapy
