My father in law has recently contacted us to move in with my husband and I who have yet to reach our 2 year wedding anniversary (he's in his early 50's). We are not in the best financial situation and we are currently trying to start recovering from it all. My father in law (FIL) receives a small check every month for disability (has been out of work since his 40's) due to who know what reason...I believe something everyone would consider not giving up your life on. He has been feeling sorry for himself all of these years and instead of taking care of himself, he has gotten into the bad habit of smoking and eating unhealthy which has now caused his health to deteriorate. My husband had told him long ago that he needs to take care of himself, but my FIL would come up with excuses, start feeling sorry for himself, and cry. Now he is doing the same thing as he has just found out that he has been diagnosed with rheumatoid arthritis. He wants us to pick him up as soon as possible because he is panicking (he thinks this is the end for him). Mind you, he lives in a different state in a small house (his house) with his sister and husband. What do we do in this situation?
Background: He's single, my husband is his only child, he has no job, and under disability.
