Hello!
I'm in a difficult situation regarding my tulpa, Tera. She has always been somewhat malleable, personality-wise. In the past, fictional characters have influenced her personality, because she would decide that she wants to be like them in certain ways. This has now become concerning. Y'see, she found out about a certain game yesterday. Now she's developing negative characteristics of one of the characters- without going into too much detail, she has become extremely possessive of my affection and attention.
As for why this is happening, I think that it's my fault. She has had insecurities that she isn't enough, that I don't care about her as much as she cares about me, etc. Last night, I tried comforting her and telling her that these are untrue. I clearly haven't done enough for her, though, or this wouldn't be happening.
I'm unsure of what I should do. Trust me, the characteristics that she is emulating are in no way positive for either of us.
