The Missing Treasures of Amy Ashton by Eleanor Ray

Former artist Amy spends her days working in an office and her spare time finding the objects that have slowly filled up her home. Fifteen years ago, Amy's boyfriend, Tim, and her best friend, Chantel, disappeared and it was assumed that they ran off together. Amy is still trying to process their betrayal and has shut herself off socially from everyone. Then two young boys move in next door and Amy discovers an antique ring in her backyard that she feels Tim bought for her before he left, and cracks begin to form in the wall that Amy has built around herself. Will Amy be able to connect with others again, uncover what happened to Tim and Chantel--and even give away some of the "treasures" that she has surrounded herself with? The Missing Treasures of Amy Ashton is a great read-alike for Eleanor Oliphant is Completely Fine and How Not to Die Alone.
