You're so right DG!
You do have to go through a process of grieving for the parents you 'wished' you had, and sometimes even grieve for the crappy childhood you've had - and then you can kind of put it behind you.
I try to remind myself constantly that I am in control of how I react in situations - no one else...... so if I feel guilty / upset / stressed - then that is my choice and I am the only one who can change that.
So Bumper - If you think your mum is being totally unreasonable - trust your instincts - she probably is - don't worry about it, thats the way she is sometimes, don't worry about it! It sounds easy but I know it's not!!! Sounds like Mr Bumper understands your situation well and it's easier for him to be objective cos he's not emotionally involved as much.
You, Mr Bumper and the lo are going to be a team soon - maybe he can help deal with your mum in the early days? My mum gets sooooo stumpped when my DH 'deals' with her - prob cos there is someone defending me - and she sees me as her property to have a go at whenever she wants to?!
And don't worry about bringing the mood down on here! This is a great place 'get stuff out there' and there are so many people on here with diff experiences in life - someone will always have some ideas / help / supportive words etc.
