Co-Parenting Help

My LO's dad has finally found himself a woman that he seems to truly be committed too, even buying a house together after about 18mths or so together. My LO loves her and she also has 2 kids, 10 & 21. She's in her late 30s, we are around same age. Lately, when LO comes home and talks about their day, I almost feel like I'm being judged on my parenting of her, some overstepping is being done. Not sure if I am just over analyzing though. When I ask him something, he'll always say like "Jane" says this, thinks we should do this or I'll have to check with "Jane". It's like he can't make his own parenting decisions anymore, simple ones even. LO has also made comments on how "Jane" says things that LO has, does or talks about are childish and she doesn't like them, then Lo will be like "Jane" doesn't like them, I don't like them. Ugh! LO is 7, still learning who they are. LO loves "Jane", the loves the other kids....I guess idk just feel like "Jane" is judging me,taking over, or kinda dictating things I guess. Thoughts? How should I go into this? Am I looking too into it and just leave it alone? Help this Mama out!!!
