This might sound pretentious or trippy. But it’s just a thing I haven’t found a proper answer for.
My paternal parts of the family are all dead, no aunts, uncles or cousins alive any longer. My maternal parts of the family suck, they seriously suck, no joke. I decided not to procreate (and had a “few discretions” regarding this) because I didn’t want to pass the shitty genes, behaviour or guilt onto another generation.
I have an ex, some relations ago. And I really loved his mother, as a mother. I was a train wreck at one time, and she saved me and took care of me. I don’t care that she isn’t my real mother. But this was several years ago.
What really hurts is that my siblings and cousins tell me that what I felt for her was fake, as she is not a blood relative. As I have helped her more than I would ever have helped anyone else. I love her, but is it true love to love someone as a mother if they aren’t your biological mother?
These feelings are so complex you could spend a lifetime untangling them.
All that matters is what it means to you.
Categorisation like whether it’s actually a mother daughter love isn’t really helpful in any way.
If you care for each other then that’s enough.
The caveat is… given your bio mums douchebaggery you should be sure you’re not “helping” this woman in exchange for her love.
