Hi swims... .

This is a sticky situation, one that I am involved with as well because I, too, have been diagnosed adult ADHD. This situation is sticky because people with BPD tend to want to blame everything on others. My wife will blame stuff on my ADHD. And it doesn't matter if you are diagnosed or not, your wife would still want to blame you for everything. Mine has at times tried claiming I have Asperger's ?
My experience is that having ADHD makes it more difficult to deal with a BPD spouse because her constant neediness is a constant distraction, and it leaves me no time to do the things I need to do to stay focused. I'm on medication, and it helps some, but does not solve the problem.
I'd suggest this:
- don't continually apologize for the same things over and over. It only enables her. No need to apologize for having ADHD.
- Read as much as you can about BPD, why it happens, how people with BPD function, etc.
- learn to validate her feelings rather than get defensive or apologize for things you have no control over (there are lessons on this on the right side of this page)
- Don't try confronting her about BPD. 99.9999999995 of the time, this will result in a very ugly rage. Instead, focus on you, and focus on learning about BPD. Diagnosis and treatment is between her and her therapist. Perhaps this topic can be brought up much later when things are calmer, but if she is in a mode of blaming you for everything, I can guarantee suggesting she has BPD will not go well at all.
I'm sorry you are dealing with this. I've been there, too. Unfortunately, there aren't any easy answers.
