Hi Dexter
It can be very frustrating dealing with parents who have issues. The constant moving certainly takes it's toll financially and emotionally.
I am happy for you to have identified that you could use some help. Good for you for seeking counselling!
Something about pwBPD is that it is not always likely that they will see they have a problem and decide to get help. Even when they do it needs a good deal of work and time and commitment to get results.
No doubt you want what's best for your mum but the first step is in doing the best for yourself.
In the end, pwBPD find it very very difficult to accept responsibility and/or blame as it hurts their fragile sense of self.
is there a particular reason you feel you need to approach her about getting therapy?And like DreamGirl says, is this something you have talked over with your own therapist?
It might be worth focussing on your own wellness to start with and making decisions after you feel you are coping with your r/ship dynamic.
If you decide you do want to go ahead and recommend therapy to her, it might be realistic to have a plan in place in case it does get ugly.
You may find it useful to read up on the communication skills DG mentioned.
There's an article about it here:
