Telling Family About My ASD Diagnosis: Should I or Shouldn't I?

For those who got an ASD diagnosis in adulthood, did you tell your families? How did they react? Part of me wants everyone to know, so I can enjoy family gatherings more, since I do like my family. I'm thinking of telling my parents first, but I'm not confident they will recieve it well. I think my mom takes these types of things on an attack on her as a mother and just goes into a weird denial (even though it's obviously not her fault). I don't live with them (I am married and live in an apartment with my husband) so it's not necessary. And I'm not really willing to do what all these youtubers say and sit down to explain everything in detail about "what autism is" to them. I don't need support from them, just the personal validation that I get to be myself regardless of how they feel about it.
