My (31f) sister (33f) is an only child and I find it hard to connect with her
For background, our dad was a hoe and got three women pregnant at once. He paid two to abort and only one did, resulting in a half sister. And the third was my bio mom who he decided to build a life with. For context, she brought two kids into the marriage with her (both by two other dads, not that it matters).
I connected with my half sister two years ago after her being kept a secret. My dad didn’t want anything to do with her until just last week. He and I haven’t talked in several years.
My question is, she was raised by a single mom and she is an only child. What I have come to realize is she isn’t really able to have (what I would consider) a normal sibling relationship. If she doesn’t like something I say, she just ignores me and blocks me out. Whereas my other sisters there is just idk, a deeper relationship and friendship. It’s so casual and we can share openly and laugh and it’s judgment free. I would really like to have a relationship like that with my other sister but it’s almost like I have to be on eggshells around her and tell her what she wants to hear. Is this an only child symptom perhaps? I’m finding it increasingly hard to want to have a relationship with her. We are very very different people. She always said she doesn’t want me to abandon her or her kids but honestly, I don’t like the way she treats me and I don’t really want to continue to pursue a relationship, mostly because it’s a lot of drama and energy to navigate her delicate perception of life and lack of grace or ability to talk through things. So I guess my question is, is this an only child symptom? And would I be horrible for not pursuing a relationship further?
