I want to be close with all my family?

Ive always been close to my mums side of family because my mum is really close to her other family,where as my dad isn't,every Saturday I normally go to both my nannans houses,but for my dads mother that's the only time I will see her in a week and compare to my other nannan and how much I see her is ridiculous.I like to be close to my dads part of family but it's hard,I've told my mum how I felt but she never listens and I told her I would rather go to my nannans sometime in the week so then I get Saturday's to myself as I like to do things with my mates.whenever we have a barbecue my mothers family is always invited and never is my dads.I guess I am lucky cause I am still close to my cousins on my dads side,but not as much as I would like to be close to them.
