Dear Prudence,
About five years ago, I lost my wife after a lengthy illness. The first year was hard, but I got through it thanks to my in-laws, who never stopped letting me know that I would always be part of their family. (My parents are no longer with us.) Six months ago, I met a wonderful woman I love and want to marry. My problem is that she is very twitchy about my relationship with my in-laws. We call each other frequently and I visit them, and their extended family, a few times a year, including holidays. But any time I mention them or my former wife—such as saying something she enjoyed doing—my girlfriend gets angry or very upset. She accuses me of still being in love with my late wife and not letting go of the past. I've tried to reassure her, but I feel that I have to constantly censor myself to avoid setting her off. I don't want to cut my late wife's family out of my life, and they are very happy I've found someone, but I fear an ultimatum is coming. What should I do?
