I have a 2 year old DS with my ex. He has been with his partner for a year now and they have a baby together - we've never met or spoken to each other face to face.
Things are fairly civil between ex and I, but recently his girlfriend has been randomly messaging me - (via Facebook) - varying from accusing me of all sorts to just random words and emojis that make no sense. She has also tried to 'friend request' me a couple of times too.
I tried to talk to ex about it, to ask why she was doing it etc and he just didn't seem to care. As my DS and their baby are half siblings, I have tried a couple of times to be friendly/civil towards her but she has no interest in anything other than accusations.
I'm not getting anywhere with ex talking to her or making her stop - I'm not BU to just block her - right?
