Dp and his ex split up 18 months ago or so.
She seems to contact him every couple of months.
He has told her not to get in contact and she resorted to contacting his parents last month.
As was told not to contact again and hadn't heard anything until today when she contacted him via message with photos of the 2 past anniversary cards he had sent her prior to the split despite the message to him saying she knows they are best apart.
We are buying a house and starting a family together and I thoughts the ex was in the past, but this is getting too much.
I don't know her, I don't want to say anything but what can I do? What should he do if anything?
Do we ignore?
