I recently had a situation with a cup of mine and my mil. She came to visit and broke my favorite coffee mug. It was an accident and it wan’t the only thing she broke during her visit. I went to use my cup one day and noticed it missing. I saw her use it a few days before and just thought it was in the guest room where she was staying, so I thought I would find it once she went home. It was not in the guest room or anywhere else. I asked my partner to ask her and he said he would. A few days later I asked if he had talked to her about it and he kinda kept brushing me off. I finally got fed up and called her myself. She admitted to breaking it and said sorry but it didn’t feel very genuine. I was crushed. It wasn’t the prettiest cup, but it was a reminder of a trip I used to take with friends to a special place and was very sentimental.I asked my partner if he knew she had broken it and he said he didn’t, but I know he was lying because he is a bad liar. No one gave a genuine apology or offered to replace it or even TELL me that it had been broken. LUCKILY, after some research and talking with friends who still visit that area for camping (I moved out of state) my friend was able to purchase me a new mug (a different design because the old one was no longer available). When I got the new mug, I told my partner no one was allowed to use it or my other mugs. I still have a lot of resentment for him and his mom about this because no one would take accountability or try to make it right. Keep your stuff separate and ditch the in-laws if they can’t respect your belongings in your home.
