Parental preference wasn’t a phase

My daughter is approaching her 4th birthday in a couple of weeks, and she still favours her father. Since she was somewhere between 18 months and 2 years old, she has had a parental preference for him. I did the googling, the research here on Reddit, and most of the time “it’s a phase, it’ll pass.” Well, here we are years later, and it’s still going strong. It’s not only annoying (today she went crazy because the man went for a gd shower), but it really hurts me. I KNOW I’m not supposed to take it personal, and I know it isn’t personal (supposedly). But damn I’d be lying if i said it doesn’t hurt. She wants him for EVERYTHING - right down to going to the bathroom (for help wiping #2) and brushing her teeth. She wants to sit by him, not me. She excludes me from things, like “me, Baba, and [baby sister].” It honestly makes me feel like shit and like I should just disappear because I’m not wanted here anyway.
