That, really. We've been together for over a year and a half but don't live together. He went off on a business trip yesterday but it was only after he'd gone that I realised I hadn't acknowledged FD at all.
I was staying at his place on Sat and his DD was there too, but I had an event to go to yesterday so left early, before she woke up.
For some reason I feel really guilty about it. I even spoke to him on the phone a few times throughout the day as he was on his way to the airport, etc. but I didn't even mention it then. It just didn't register. Even though I called my own dad of course.
Should I have done something? Like a card? What do other people do when their partner has a child but you don't have one together?
