It seems to me you have gone way above what could be expected in an effort to keep in touch and be a good daughter. If your mother is anything like mine was, whatever you do will not be good enough and there are other daughters who treat their mothers much better.

The only thing I could suggest is to copy and paste some of the information that you email to your in-laws and print it out in a letter to your folks. Don't expect an answer, just send the letters. It will be less expensive than trying to call and you will not have to get upset by whatever comments she may make in talking with her.

You are a good and caring daughter and for you to have helped with their retirement home is outstanding. I personally absolve you of any guilt that you are feeling.
