Well, that sounds great, Portia - I'm sure all will go well. But I think the clue as to why she just wants to go with her boyfriend is because you feel "just as uptight" as she does. She will be aware of this and, as well as wanting to do well for her own sake, she also feels a responsibility to you as you have such a stake in her future as a loving, concerned Mum. She doesn't feel any such responsibility to her boyfriend so she doesn't mind him being there when she gets news that might be disappointing. It is because you and she are so connected (in a good way) that she wants to do it like this. It is absolutely not a rejection - it is just the opposite, so don't feel hurt.
