Hi FirstSteps, welcome to the group -- glad you found us
Two teens, huh? My husband also has a 13 year old & 15 year old, and their mom has many BPD traits. So, you have a full plate, to be sure!
Good to hear you are getting therapy. Are the kids also in therapy? Is your wife? If so, does she seem compliant with the T, and accepting of the T's input?
It would be a tall order for anyone who recently "discovered" BPD to juggle all these pieces you mention: facing her rage while setting calm, consistent personal boundaries, without "falling off either side of the horse", whether too apologetic or too argumentative. Oh, and parenting teens.
What I notice, though, is you have awareness and acceptance that you have played a role in your family's dynamics, and you want to change.
It's ok to make one change at a time, and it doesn't have to be the biggest thing, to start. Marathoners start by running shorter distances -- nobody runs a marathon for their first race ever.
We can walk you through practicing some new tools and skills in one or two areas, to "build those muscles"; then, as you gain confidence and familiarity, you can tackle other challenge areas.
It's ok to not fix everything at once. You have a great start and are motivated. Let's do this one step at a time.
As you think back on the challenges in your marriage, what are some of the "big" ones? You mentioned her rage.
Now, what are some of the smaller ones, that are still kinda BPD-ish? Maybe 3-ish of each for starters.
And to your final thought, about getting your own house in order -- again, I hear your desire to make things right, to do the work and fix things. You know how on airplanes, they always say in the safety trainings that you have to put on your own oxygen mask first, before you help those around you? That is a big part of having a better relationship with a pwBPD (person with BPD). As "selfish" as it sounds, we really are in no position to start making things better unless we take care of ourselves first.
So, that being said, I'm curious if there are some things you do to chill and decompress -- hiking? Reading? Music? I wonder what it would be like if you took even just 5 minutes tonight or tomorrow, just for you, to recharge.
Looking forward to hearing back, and again, welcome;
