Hi Aerials,
I am so happy that you have lots of supportive friends and family members, and congratulations on getting married and having 3 beautiful babies! That sounds like a busy and happy 7 years!
My husband has been telling me for years I should see a therapist, but I have been telling him that I did so in my 20's, and it helped to get me to the NC decision and for that I am grateful and all done. What else is there? Nothing is going to make me magically have memories of a happy childhood. But last night, yet another story of abuse sort of popped up in my brain as it was related to a topic my husband and I were talking about.
Aerials, now that you are a mother, it makes sense that memories or stories from your past are more likely to "pop up". I think that's natural.
Do you have any reservations about going back to T?
Maybe it's because now that I am middle age and I have the most memories of my mother at this age, I remember stuff and think, "How could she have said/done those things?" The anger I felt in my 20's that propelled me to travel far away from her is now no more effective than yelling at a rain storm. What is a next step or goal if I go back to therapy?
In my experience (esp. over the last 2 years), I remember being aghast and angry at the things my mother would say to me, or how she would manipulate and twist things, or try to make me feel bad, or be outright abusive to me. I was so angry, frustrated, outraged, and hopeless... Then one day I had an epiphany that it was never going to change. And I had to accept that it was never going to change. Eventually I figured out her thinking was distorted...a form of mental illness...and instead of trying to show her what was wrong, or make a point, or try to change her, or make rational points to "show her",... I just had to accept the situation wasn't going to change, and change how I reacted to her. It's helped me a lot. It's not a magic bullet, because when she goes off the deep end, I still fall a bit too, but I don't fall as far down, or as fast. I have learned tools to navigate a relationship with my mom, as I am her primary caregiver, and she is a frail and severely damaged needy 85 year old who lives independently and has refused assisted living (pre-pandemic). So when you ask, "what is the goal if you go back to therapy", I'm going to throw out a few suggestions, which others can add to, and maybe there will be a "nugget" in someone's suggestions that you can latch onto?

- radical acceptance?
- resolve the feelings? (which surface with the memories from your childhood as they pop up now that you are a mother). I think this resolution is important for a few reasons, but if you can effectively allow yourself the negative feelings, and work through them, it could result in a greater sense of overall wellbeing (not that you aren't already "well", but presumably some part of the psyche is affected if your H has been suggesting for years that you should see a T

). We benefit from "resolution", but so do our loved ones around us.
- self-improvement? For me, this meant learning new skills for how to deal with my mom so I could manage my relationship with her in a way that was healthier for me. I wanted to be happy, and not always in "crisis" because of my mom.
What else is there? Nothing is going to make me magically have memories of a happy childhood.
no, there is no magic that can change our memories. But with work, we
can learn to manage the feelings from those memories, and thus move forward in our life.
Personally, I no longer have the anger, frustration, anguish, hopelessness that I used to feel (most of the time). I can still feel profound sadness and regret that I don't have the mother my friends have. My friends have such healthy warm relationships with their moms. Mine feels superficial. While I still love my mom, it's a kind of detached love, but it's accepting of who she is. However, I can still look at my life and feel gratitude for the things that I do have (great H, 2 great adult kids, career) and recognize that on balance I'm still fortunate, despite the "burden" and sadness that comes with having a BPD mom. Today is a good day, and so it's a lot easier to write that. A month ago at my last T appt, it was a very bad day because of my mom, and I probably wasn't going to post a reply to anything on this board. But maybe I'm feeling 80% (?) better than I used to 70% (?) of the time? I can't say that was my goal when I started T, but it's still a pretty good outcome (on a good day). To answer you question, on when does a person feel 100% healthy and happy, I would turn around and ask if that is realistically possible!

I'm sure you meant it as a figure of speech, but a lot of us raised by a pwBPD have perfectionist issues, so I would suggest lowering your standards! haha
Just some random thoughts about possible goals for T.
Again, congrats on a marriage to a supportive H, 3 beautiful children, and great friends!
