So jealous of my future SIL and BIL at the minute. I know it's wrong but it's eating me up. Bit of background, over the last two years they have bought a fabulous, quite expensive home and decorated it completely including, attic conversion, garage, garden etc, mortgage will be paid in 5 years, had a new baby and got engaged... The ring is huge. I'm very fond of my sil but I'm jealous. How can I overcome this. I need some perspective please.
