Im tearing my father’s relationship apart because I am not caring towards his gf of 2 yrs since I feel like she is replacing my mother who died 3 yrs ago. The gf wants to break up with him because I “hate her” and “always gain her a dirty look and attitude”. I don’t remember ever being explicitly rude to her but I do see how hard she is trying to get close to me but I don’t care because I don’t really like her.
