It's like another obsession she has at the minute is she is always trying to invent a dramatic life story for herself and keeps trying to claim that one of her parents wasn't her parent but we both did ancestry DNA tests and it was bang on the button that my grandparents are my genuine grandparents and her parents! Yet she is ignoring that.
Hi there,
Inventing a dramatic life story sounds like typical BPD to me. It could be a bid for attention--YOUR attention--typically of the sympathic-pity sort. In addition, your mom might crave drama, as she finds it stimulating, and she gets a reaction out of others. She might be trying to develop a victim narrative--My real parent abandoned me, it's so unfair, poor me, no wonder I'm such a mess, it's THEIR FAULT! But my guess is that saying her parent isn't her "real" parent is code for, "I never really bonded with my parent and I'm upset about that." Is she talking about her mom? Not bonding with the same-sex parent can feel especially traumatic.
I think my natural inclination in this situation would be to ignore the whole narrative. But sometimes validation is recommended. You might say something like, It would be disconcerting to feel your parent wasn't there for you, and then see where it goes. If you're feeling charitable you might say, Well I'm glad you're my mom and I love you.
On another note, I have an elderly relative in my life who is a "dreamer" sort. Since I lie on the opposite end of the spectrum (I'm a doer and more logical/less emotional thinker), I found myself being bothered by her "fantasies." An example is when she'd talk about getting married again--in her mid-80s after being single for the last 50 years. She talked about a wedding, honeymoon, etc. when she barely leaves her house, let alone date anyone. It just sounds completely DELUSIONAL. I found it was best for me not to engage in this sort of talk, because it would make me upset, talking about fantasies like that. But she's going to do it anyway, because I think she likes living in a dream world. Since I don't, I try to refrain from egging her on when I'm with her.
