No, DH is my best friend followed by my sister.
My mom & I talk frequently - less frequently than we used to, & I value her support. I know she loves me, & I love her. I am thankful & grateful for the sacrifices she & my dad made for me & my sister while we were growing up.
On the surface, yes, we're probably "friends," & we do things together. I ask her for advice on "superficial" things. She likes to shop & browse, while I don't, but, many times, I'll ask her to go with me to the mall whenever I'm looking for something because I know she enjoys it. We vacation with my parents sometimes.
However, our relationship is also complicated - not to her, but to me.
I harbor a lot of bitterness & resentment towards her for some things, yet, at the same time, I love her & am very grateful for her.
She's judgmental & very passive-aggressive. She was always impatient & yelled a lot when I was growing up. She's much nicer & more patient now - she also much more "fragile" now, emotionally, mentally, & physically. While to everyone who knows her, she is a wonderful mother & grandmother, there are some things from when I was growing up that still affect me - how I view myself, how I parent, etc.
She also uses her grandchildren & gets a high from being the #1 grandparent (even over my dad) in their lives. She has no life except for her grandchildren.
I don't say anything to her, because, at this point, there's really nothing that could be done that could change things, if that makes sense. However, sometimes, I'd love to talk to a therapist or someone just to come to peace w/ my "mother-daughter" issues in my own head.
