Ex NPD/BPD's New GF Moved In with Him

[I_Am_The_Fire]

So I found out a few months ago that not only does my ex (NPD/BPD) have a new girlfriend but she moved in recently and that's when the kids (D14 and D7) met her. Her teenage son also moved in (S16). So far everyone who has met her tells me she seems nice and the kids seem to like her which is good. A few months after I found out about her, I invited her out to coffee so I could meet her.  She declined saying she's not emotionally prepared to meet me yet. Not really that surprised. This was all via text. I told her that's completely okay, it's not a problem, and that I look forward to meeting her one day soon. I found out later on from D14 that the new GF thought it was weird that I wanted to meet her. My D14 also told me her dad (my ex) thought it was weird that I want to meet her and so does our daycare lady apparently. I thought it's normal for a mom or dad to want to meet the ex's new partner who moved in and is now a part of the kids' life. Is it weird?

It's not weird given school aged children,  even teenagers who might be semi-independent and close to legal adulthood.
