Thank you Daniel.
I do what you suggest but at the same time I feel like being silent is like accepting what is not acceptable.
Even if I don’t answer such SMS, they still hurt me… I feel then thorn apart
Being silent doesn't mean you are accepting of their behavior. When my wife tries to "stab" me with a comment or try to take whatever she is dealing with out on me, I immediately cut off communication. If we are in person, I stay calm, validate if I can, and be quiet if I have to. If I am able to, I leave and say we will talk about things when we are calm. Protect yourself!
