Stressful. I love my mom but more than a 3 day visit and I’m pulling my hair out.
They sound like they have options even if they don’t want to see it that way. Your mom may have to find a job and your dad could find work with other “brothers” couldn’t he?
I would take in my mom if I had to; she is on disability and hasn’t worked since I was 4 or 5. She is fine where she is, but it could be necessary in the future to take her in.
Your parents may be looking for the easiest solution which may be, to them, move in with you. You might need to subtly but firmly recommend selling the house and both finding jobs. If it becomes necessary, set a limit 2-3 months? on how long they can stay… if it comes to that. I feel for you. This will not be an easy situation unless your dad gets a good job and quick.
