I'm very curious about how this played out, as we had something very similar happen but over something much more minor.
SDalmost9 told us that BM wouldn't let her use knives at BM's, even though SD has been cutting her foods with a knife for 8-9 months and has even begun making salads with a paring knife in the last 2-3 months. Now, we accepted that as sounding like how BM would act because BM has been infantizing SD somewhat - not wanting SD to be told about how her body is developing, not wanting SD to have t-shirt type coverings that look something like a sports bra, even though SD is developing a bit.
So, last week we decide to tell BM about SD's knife usage here in hopes it would encourage BM to let SD grow up a little at BM's. DH tells BM about SD cutting her foods. BM looks at SD and says, "You told me you weren't allowed!" SD just has an 'uh oh' look on her face. DH tells BM about SD making salads. BM says, "All right, my girl. You're going to start doing more stuff around my place, then." So it turns out that all this time SD has been telling
us that BM won't let her use knives, and telling BM that
we won't let her use knives!
I spoke to SD's therapist about this and she says not to get too upset about it. It's just the divorce version of playing one parent against another.
Anyhow, now it makes us wonder about a lot of stuff. Like right now BM is apparently not letting SD phone us on weekends - which would be a normal MO for BM, since she just told SD not to call her on weekends anymore. BM tends to make unilateral decisions, and if she's going to cut SD out of calling her she'll also cut SD out of calling us. But when we said something to BM, BM says SD is lying - which now after the knife thing we can't be completely sure who is telling the truth. Fortunately we still have CPS involved (after BM's BF abusing SD), so we can let CPS put their foot down on the phone call, whether SD is telling the truth or not.
