((((AI)))) Dear ... the most important thing right now is finding as much peace and comfort as you can - for both you and baby girl.
I hear you... since the family is now getting involved, you feel they are going behind your back which is creating added stress for you right now.
Is it possible to have a family meeting? Or to send a note to everyone letting them know that you understand they are confused, upset, frustrated, etc and appreciate that they care so much as to "protect you" from any further pain. But right now you really need them to totally focus on you and the baby. That their involvement, although greatly appreciated, is creating even more stress for you.
Then ask them with all sincerity for what you really need from them right now / whatever that might be: perhaps...to keep you feeling calm, safe, and as healthy as possible.
That you love them and understand but that you are managing things with your stbxh the best way you can...and to please just be there in the moment right now for you and the baby.
It sounds as if they are circling the wagons on your behalf.
But you need to be in the middle of that circle! Both you and baby girl.
Again, you have done nothing wrong. You are lovely and beautiful. Let your family know what you need right now to help ease your pain and confusion. They do love you and want to be there for you xx but what is now happening is adding misery and not comfort. Even with the best of intentions!
Maybe you can even write a list of things and delegate tasks to everyone so they are still involved but focusing soley on you and baby
Hugs, Rose
