Am I being selfish and heartless?

Stay with your family, the few extra days. Your husband will understand, you have a lifetime together.
Your family, will be really upset that you are leaving anyway, be that in a few days or whenever. It will be another happy memory, for you & your family to look back on.

I agree. It would be nice to leave without worrying you made your family disappointed, somehow you will miss your family when you get to UK and you will regret it that you turned them down.
Yes, your husband should be your priority, but am sure he wont mind if you will stay for extra more days with your family.
