this isn't quite the same situation but my mom (a widow) went thru breast cancer just this august and naturally my sister and i took care of her. my sister had been dating a new guy for a couple of months and was just gaga over him and told me she thought he was the one. my sister is in her 40s and this guy his early 50s. the guy decided he needed a break from their relationship the day before my mom started radiation treatment. then, a couple weeks later he started up the relationship again with my sis--right after my mom's treatment ended. i haven't talked to my sister about it because we aren't that close, but i keep telling my mom this guy is so not the one for my sister. i think my sis is finally seeing the light as she's started to date other guys as well.
