Hello Lalaland123,
Welcome here !
I have a mum with BPD as well as a grandma, so I can relate.
Have you heard about FOG ?
https://bpdfamily.com/content/emotional-blackmail-fear-obligation-and-guilt-fogChildren of BPD are taught to feel guilty / obligated whenever they don’t meet the needs of the BPD parent. Personal boundaries are not allowed. We have to live for them !
I think it is for a good reason that your siblings are not willing to take your mother in.
It is of course only my personal opinion, but I would encourage you to think very well if this is what you really want. Is it really ok for you to sacrifice your peace of mind, the peace of mind of your husband and the one of your children, for someone who will most probably cause turmoil in your household ?
Your son is on the spectrum. I imagine this is giving you a lot of stress. Even ‘normal’ children in a ‘normal’ household sometimes ask a lot of us. Add a BPD grandma to the mix, and there really is a lot to deal with (I speak from experience). Invite the BPD grandma to come live with you and I don’t think there will be space left for everyone to just enjoy each other’s company.
You will have to cope with an awful lot. You will have to explain things to your son that are unexplainable (been there with my daughter). You will be stressed out (you already are, understandably). You will sacrifice your family for a mother you probably wished you had – but never will have (sorry for sounding harsh … I guess us children of BPD at one point all have to accept that we will never ‘really’ have a parent. We hope and we hope and we do whatever they want us to do, we cross our own boundaries, and often we don’t even have boundaries. All in the hope that we will finally get the love we never got from them as a child. Until we realize we never got it, because they cannot give it, they are simply not the parent we wished they are. And crossing our boundaries time and time again is not going to change that.)
I am not judging you. And this is only my opinion, there are probably members who think otherwise. But personally I think allowing your mum to come live with you will take a huge toll on your family and on *you*. Your children need sanity to grow up with. I don’t think living with a BPD grandma could possibly give them that.
Their grandma will have a huge impact on their daily life and will for sure also have an impact on their personality, like you and your husband will have. But do you think that's a good thing in case of someone with BPD ? Are there things your children can learn from your mum ? Will she have a positive influence on the life of your children ? Did you grow up to be a happy, balanced person after having lived with your mum as a child ?
I hope you don't think I am sounding too harsh, and please excuse me if I do. I just want to show you that there is also another way to see this, and you are in no way obligated to do the impossible.
What do you think ?
Do you have a therapist who you can rely on ?
Again, welcome here, we understand
