I am in the same situation: Roughly at a time where I moved to a new house I decided to loose weight (133kg). In 2.5 years I lost 40kg, for 6 months I stayed in a plateau, then in the next year I regained 20. Since two years my weight is more or less stable. Today I am, like you, not sure why I loose so much weight, why I had a plateau, then why my weight went up again.
