I too have a hard time of developing a good relationship with my mom. I take it personal cause I am adopted and have always felt that I was not loved or treated fairly. I am not the only one that sees that she treats me like this. I usually bring up the past and she don't remeber either but when it is convient for her to protect her son she has the best memory. Seems to me that she has a memory of convience to benefit what she thinks or needs. I just have to accept that she is who she is just like I am who I am. It's hard cause everyone needs their mom in their lives. So I am sorry for what you are going through.
