Having a parent move in with us, due to their age and situation is healthy, common, and appropriate. Many cultures do this world wide, instead of putting them in a care home. Seniors who spend time with their grandchildren tend to live longer and happier.

I also think it's nice and appropriate to invite them on family vacations. They're often lonely and may have limited purpose in life, tire easily, etc.. particularly if they've been widowed.

So, to answer your question, yes it is healthy to request this.

I can understand why you're feeling resistant..

1) Your age. It's a big responsibility to take on at such a young age and I wouldn't advise it for you.

2) There's other concerns going on with him. It could be cultural-based or something to be heightenedly concerned about. If you're picking up on red flags, bail out now.

I am his age. I've been through many things in life and can tell you with certainty, you will be facing a lot of hardship if you choose to stay in this relationship.

I'm sorry.
