Last year, my husband and I went on our honeymoon and left a key to our house with my in-laws on the chance that something inside would need tending to while we were away. The whole time we were gone, I felt uneasy about them having a key and possibly looking through our personal items. Everything was fine, though, and they gave our key back when we got home. Fast-forward to our vacation last month. Remembering my feelings of unease, we decided against giving anyone a key. While we were away, my husband emailed his parents a few times and, in one of those emails, mentioned that we had forgotten to bring some plants over to their house for watering. Well, his dad told him that he had made a copy of our key while we had been away last year and could let himself in to water the plants! Prudie, I am beyond angry and feel that my trust has been irreparably damaged. Am I warranted to feel this way? How should I approach them?
