Separated end of last year. STBXH has established a 'relationship', but won't admit it. I have no idea how long it has been going on, or if there was an 'overlap' as I discovered he was online dating. He continues to deny there is a relationship, even though he wanted to take dd (14) to stay at her house on one of the overnights. I objected to this, so Woman came and stayed at his! Typical of how he has got his own way by stealth for 20 yrs really. She has come back from hols, and brought dd a bracelet. And i just feel a bit Sad (?) that another woman has a sort of parent role with dd, and he won't even admit to it. Given that he lied to me for 20 yrs, this is not a suprise, but... :(
