i am so sorry for your loss debi. but i've learned that wondering "what if" will not change anything and will only make you feel worse. you did everything right just by being by your husbands side and loving him. that's what matters most. my mom always tells me that "when it's our time, it's our time" and nothing that we do will change that. it is our fate and destiny to pass when we do. i believe what she says is true. and i believe that you did everything right and that your husband was grateful and blessed to have you by his side until the end. i pray that you can find peace and joy in the memories you shared together. soft hugs and prayers are coming your way.
