DD(20) popped round to her GM's home yesterday. Let herself in and started calling out to find where in the house she was, her biological father replied, she was surprised as she didn't expect him to be there, found where GM was talked and then went and sat down in the living room.
In the 90 mins she was there he not once came into the room to talk to her and in her opinion went out of his way to avoid any contact, even running past the door way so he wouldn't be seen.
Later in the day she had to go back to GM's house and spent another hour there, he again spent the entire time out of the room, apart from 30 seconds when he asked his mother something, he still did not acknowledge DDs existence.
DD and him do not have a good relationship, the fault does lie with him, but AIBU to think that no matter what the relationship is you still, as the parent, acknowledge your daughters presence and at the very least say hello how are you?
