Dear Prudence,
I am a woman who has been married for 15 years, and I have a 13-year-old child. I have been in a long-distance love affair for four years with a single man almost 20 years older than I am. Our plan has always been to wait until my child is out of high school (four more years) before I divorce my husband and we begin our life together. I know I am not going to be viewed favorably because of my affair, but now I have a different problem. My lover recently had a stroke, and chances are not looking good for a full recovery. I very much want to spend whatever years my significant other has left with him. Our plan was to ease into our full-time relationship while causing the least amount of damage as possible. But now I don’t know what to do. Any advice?
