@PinkCrayon totally agree with the dramatics, visualising a poor wee 5 year old’s eyes welling up because her Xmas baubles are missing. I find it highly unlikely that the daughter (or her father) give two hoots about her supposed precious Xmas baubles. The baubles & the tradition around them are, quite obviously very important to the OP & she says she imagines her daughter being disappointed at feeling left out, rejected, not part of Xmas.
I think these are the feelings the OP is having & is projecting it onto her daughter. Kids are quite easy to distract around Xmas time, it stands to reason she cares much more about presents than about baubles.
This is an opportunity for daughter to learn about how people celebrate in a variety of ways. To think this girl’s Xmas is going to be destroyed because she is going to wonder where her baubles are, is quite honestly ludicrous & can only imagine the daughter will care if her mother is making it a big deal that it’s not a proper Xmas if her baubles aren’t hung at both houses. The OP mentions being in tears last Xmas so it’s clear traditions around it must be of quite importance to her.
In my experience in my country as kids we would make decorations yearly at school...It stands to reason daughter might make her own decorations for dad this year ? It doesn’t need mum’s involvement. People pick their own mementos for keepsakes. He might keep something of hers OP doesn’t even know about. Does mum really need to provide something to dad as a keepsake? Let him pick his own!
I think OP is being labelled “controlling” but she doesn’t mean to be, but she is micro-managing & trying to make suggestions when they aren’t welcome. she isn’t barking orders, but she is overstepping boundaries & this is why it has become an issue of control.
I think she is used to being the most important woman in her ex’s life. He is a great guy but a shit partner, her exact words ? So when he gets serious with someone, it hurts because she has essentially been usurped. The whole “buddy buddy” Schtick often changes when a new partner comes on the scene.
The OP keeps referencing how her ex cheated on this woman. I think it makes her feel better, the narrative is that he is a bad partner & he must not like her that much & this won’t work out.
She lacks respect for this woman, which is not a great place to be when this person is involved in your kid’s life. Let’s not forget the original issue was OP refused to look at the gf in the eye. That’s quite passive aggressive to avoid all eye contact & actually takes a lot of emotional effort to keep up.
I also think the daughter sharing a room with the gf’s youngest is quite cute & sisterly. I always wanted a sister & that to me sounds nice & inclusive.
