My DH and I have been together for 8 years (living together 4, married 1). My parents are very involved in our lives and visit often (both me and DH are happy with this) and the rest of my family have accepted DH with open arms and treat him like one of their own.
My MiL however is barely on the scene. She lives 3 miles away, drives and has no job so has no reason not to visit us but has been to our house twice in 4 years.
She absolutely adores DH's brother. Visits him all the time, invites him over for xmas, buys him new things for his house but has absolutely no inclination to do this for her other son.
Can you think of any way I can try and get her more involved in our lives? I am always polite to her and have invited her to our house so cannot see what the problem is.
