First of all, your friend is a very good friend. If so, your boyfriend will be there when you go, and she will definitely talk to you and your boyfriend. Therefore, no matter how busy she is, she shouldn't have what you said: a day has passed and she hasn't asked your boyfriend yet.
In the second case, she and you are friends, but they have not reached a particularly good relationship; I was very busy when I first got married, so I forgot what I told you before.
So, on the whole, we should weigh the relationship between you.
