The BP problems, if he’s taking his medications, shouldn’t be a problem. Some people have bad swings in BP, but its usally because their med regimen needs tweaking and it’s just a matter of trying out some new drugs until you get the right combination. If he’s not controlled, and he’s falling, etc, then best he live with you.
Your mom’s cancer - if it’s been taken care of by chemo/radiation - shouldn’t be a problem for her to stay at home. If it’s active, and she’s symptomatic or could be symptomatic any moment - best she stay with you.
I wouldn’t fault you for keeping your parents.
I’m talking about the guy whose mom can run a marathon and dad goes to work every day, and he can’t part from them and that’s why he wants wifey to live with them.
Someone also made a good comment. It depends on whose house it is. If it is your parents home, then it makes your wife uncomfortable because the home is not hers to decorate, etc as she wants.
If the home is yours, then your wife feels more in control, and the parents can just come and live with you, but remain cautious because if parents feel like they are taken out of their homes to live with their kids, their course can be even more downhill from feeling depressed and helpless in taking care of themselves. Sometimes, their own home is the best place for them.
Tough situation, but most girls will probably work with you on that, unless your parents create padhas. A pretty bad thing to do when you have cancer and BP problems, but plenty of people misbehave despite being sick. Plus cancer patients will have psychiatric changes on their way out. I knew a lady with cancer once, and she went ballistic right before she died.
Research the diseases, know what you need to expect, and properly inform your rishtas about the situation, and only go with someone who respects your situation.
