How long have you been together, how longing have you been in her life and how well do you get along?
All this will have a significant impact on the dynamics of the family.
There are 3 dynamics: You act as a family and all activities are done together. This is fine if you've had the chance to get to know eachother well and you all get along and are happy to spend most of your time together. Possible, but at 16, not as common as if she was 6.
Or you accept that she wants time with her dad without you, because maybe you've rushed a bit into her life and she hasn't had enough time to accept you in her life but you are jealous of the intention she gets and expect your oh to give you as much attention as he gives her when she's there. In this instance, assuming she's there eow, you might need ask yourself why, if you have his full attention 12 days out if 14, you need it to a high extent on these 2 days too.
Or you accept that she and you are not very close, or that you don't really enjoy the things they share, or appreciate that they have a bond that they share when it's the two of them and that without removing yourself completely for 2 days, you use most of it for yourself to do the things you don't otherwise do.
The latter shouldn't mean ignoring eachother completely of course but just taking a step back. Going up and expecting him to check in you is passive aggressive behaviour and won't help in anyway.
Hopefully you'll find the right balance that suits the 3 of you.
