When he won't tell me what to get?
Mil is extremely fussy and, imo, ungratefull. If you get the wrong thing or don't spend enough she will say "Well I thought I'd have got more than that" or "WHy did you get me that? You needn't have bothered if that is all you come up with"
DH is also very moody and agressive and if I get the wrong thing he will go in a mood with me too.
So AIBU just not to bother? I did say I would go and get perfume if he found out which one she liked but he never bothered.
