@vera Exactly. It’s not about her being a single working mom… it’s about how she treats her adult offspring like a two-year-old after being absent for their entire life. It’s made clear that Rebecca wasn’t overly affectionate or involved much in her kid’s life growing up. She’s not a very warm person, to begin with, and given that she was all the MC had growing up, certain personality types would not do well in that environment. Therefore, they would now be distant with her.
But, despite the distance between them (the reasons for which Rebecca herself seems to understand), she expects the MC to just welcome her into their life with no question because “now you know the truth!” It doesn’t work that way for a lot of people. You can’t just lie to someone their entire life, be lukewarm with them, and never really be there for them, then expect them to trust you because you were finally honest with them. Throw in the fact that she still isn’t honest with them about the father and is trickling information to them, and there’s really no reason a detective who wasn’t previously close to her would suddenly decide she walks on water (which is how the narration, UB, and everyone else in the series seems to act).
So, again, it isn’t about her being a working mom. My dad traveled three weeks out of every month when I was growing up, but he and I were still very close because he was there when I needed him and, when he was in town, we spent a lot of time together doing all kinds of stuff (usually with my mom complaining that he shouldn’t treat me like a boy, lol).
That is not how the relationship with Rebecca is presented in the text, and she’s just… cold… most of the time. Bouncing between cold and “I’ll do anything to protect you!” gives me (the reader) whiplash and comes off to two of my MCs as a load of bullshit and totally unbelievable. She also expects the MC to act like a child, allowing Rebecca to take over their “safety” or whatever, and is completely disrespectful to the MC in front of UB, with whom the MC is trying to build a working relationship.
Anyway, tl; dr: it isn’t about Rebecca being a working mom. It’s about Rebecca, both her attitude and her actions. That’s why I don’t like her as a reader, and why two of my MCs literally can’t stand to be in the same room with her. Unless she starts treating them more like the competent and skilled adults that they are, instead of dimwitted children who can’t tie their own shoes, they will never be able to tolerate her.
