They make some awful comments. Imnjot really 'allowed' to mention my partner or their (adult) children (whom I'm involved with) but rather than being overtly awful, it's more the erasure of our existence, our relationship. It isn't seen as real to them because same sex relations aren't right, and people who have them have something wrong with them. If I protest I'm told how much they've been through with them having to deal with learning I'm gay, and how I should be grateful. I think I'm cis too? Unless I've misunderstood the term, I thought it was more to do with gender.
It's many small things together. We have a family whatsap group for example and if any of us do anything (days/nights out usually) we add photos and everyone comments/questions. If I put any up, they're ignored unless it's just me by myself (others are with my partner and/or her children, I rarely go out with anyone else). When her children visit I'm told not to bring them to my parents under any circumstances, they want nothing to do with anything to do with her.
I am trying to distance myself but I'm finding it difficult, I don't think I'm ready to fully do it yet. It's not easy.
Most accepting, my sister. Although I've learned she's said things to other family members that aren't nice so I don't know.
I'm basically not seen as a real person.
