Im debating whther to tell my meta that our shared partner has been going barrier free behind her back...

Would you want to know (and hear from your meta) if your long term NP and father of your kids had been consistently going barrier free over the entire course of your relationship with you (26 years) and not informing you of such?

I'm really struggling with whether to tell my meta this. (Soon to be ex) Partner says this behaviour has stopped, and we have always used protection except for once. But I dunno. He did it for decades. I certainly don't trust him anymore, but I feel too "in it" to make a good decision about whether to inform meta.
