Hi AloneInThis,
I'd like to join Turkish in welcoming you to the site. I'm so glad you found us, as I'm sure the information here and interacting with a community that can understand your difficulties will be a huge support to you, as it is to me.
One of the biggest frustrations I have in accepting blame to end a conflict, is that I know it creates a momentum shift where the unacceptable behavior becomes acceptable. I feel like my partner grew to resent me for this.
Whilst it is noble to want to keep your partner 'on a level' and avoid escalation in dysregulated behaviours, one thing I learned that helped me so much was around validation. Specifically not validating the invalid.
It's really useful to steer clear of JADEing (justify, argue, defend, explain), and rather than using these, good use of validation is a skill that, when practised can allow us to sidestep taking undue blame on ourselves, instead cuts to the emotion that our partners are feeling and what is causing it. The outward behaviours, accusations etc. are just a means of venting that emotion. There is a really helpful video here that made lots of sense to me, and I hope it does to you too if you've not already seen it:
https://bpdfamily.com/message_board/index.php?topic=206132Once I began applying validation to our communication (it took practise and was hard at first) I found it had positive results. We were able to move through his triggered emotions to continue with a reasonable conversation. It's clear you're both looking to improve the way things are playing out for the benefit of your child and I hope that this can help for you. Once you get good at validation you can also use it to validate yourself, which is important!
It's encouraging to hear that your partner has identified that she has some issues. Would she be open to seeking a professional diagnosis and some recommendations on how to manage coping with her traits? If you find that the couples therapy is not as effective as you'd like, perhaps this could be an option.
Keep reading and posting. This site is a gold mine of helpful resources and valuable support from others in similar situations. You're not alone.
Love and light x
