I've been having issues with my mother for many years now, and I cant take it any more. I've reduced contact with her and have now written this latter explaining why. Not sure how to end it though 
(Note: me = Sarah; Lily = my 2 year old DD; I also have a 7mth old DS).
Dear Mum,
I am writing to you because I feel that our relationship may be un-repairable and I fear for its future. There is an engulfing climate of disrespect that I have experienced from you since I can remember, but which has got progressively worse since Lily was born. I feel that you treat me like a child and are not capable of respecting me as an adult. This is evident in your words (for example, ?Sarah I WANT you to do this for me?) and it is evident in your actions (I spent days photographing, listing, packaging and posting your stuff to make money for you ? time I could have spent with my children, yet I never received so much as a thanks from you).
When I conceived Lily I wanted it to be an opportunity to get close to you. However as time has went on I have found that your input has been overwhelming, and you have gradually started to take over. It has came to the point where I can?t tolerate the discomfort anymore ? it feels as though you are pushing me out of the mother role and inserting yourself in it. Instead of being Lily?s grandma, you are attempting to be her mother. Sometimes you even refer to Lily as ?Sarah? and yourself as ?mammy?. This is not healthy behaviour. Neither is the fact that you changed my old bedroom at your house into an entire nursery for Lily, complete with pram, cot, clothes (some of which you reserve for only when you are with her), toys, bottles, bath, highchair. It really is like you are using Lily to replace me.
I also feel that your love for me dissipated once Lily was born. I was merely a vessel to produce Lily, and now I have served my ?purpose? I am just an inconvenience to you, and a roadblock to your hold over Lily. This is in part evidenced by the way you undermine my decisions and confidence, particularly in relation to my parenting.
For example: when I explained how to deal with Lily when she was having a tantrum, you did the exact opposite, and continued to defy what I was instructing; Consequently the tantrum went on much longer than normal and Lily got more and more distressed.
When we are together, you spend a lot of time arguing with me over every little thing, often in front of Lily. It is unhealthy and confusing for Lily to witness the constant undermining of her mother. The volatile relationship between you and I is not a good mother-daughter role model for Lily to witness. You attack my parenting (example: when I had postnatal depression you said that my crying was damaging to Lily; another example: when I removed a dangerous broom from Lily and she started to cry, you accused me of hitting her). I find these attacks belittling, hurtful and hypocritical. It angers me that you can attack my parenting and accuse me of ?damaging Lily? even though I have never come close to doing what you did when I was a child (attempting suicide and sending me to live with Anne). Sometimes you even try to compete with me (example: when Lily has a tantrum you say, ?Lily never does that when she?s with me?).
It has got to the point where I feel uncomfortable, angry, dominated and belittled with you more often than I do not. I feel that taking a break from you has strengthened my relationship with Lily, increased my confidence, and made us calmer as a family.
I am 30 not 3, and I need space to find my own way as a mum. You had your turn with parenting ? now this is mine.
