JinMay : yes, talk to your boyfriend about it but know that it is okay for you to do something for yourself and it is okay to ask your other family member's for help. They also are part of the family & helping each other out is a blessing in itself.
So many of my older customers get fatigued caring for their ailing spouses it is very sad to see. I don't want that to happen to you, then you are of no help even to yourself. You have a long road ahead of you still with the surgery and recovery time so if you have the energy then do something fun with your boyfriend. And ask for help, put structure in place for others to follow... if you got sick they would have to so prepare them ahead so they aren't floundering if they suddenly had to take over. I know they are younger but they are capable of some tasks. How about Aunts or Uncles?
