Hi Ew,
I"m sorry that you are struggling in your marriage. You have found a great place for support and advice. It sounds like you've started to use some communication skills that have worked modestly, but are still struggling with not taking what your W says too personal. Am I correct in seeing this?
I know it's really hard not to take offense and hurt at the things our pwBPD says to us because what they say hits very personal areas. When my H does this I remind myself that he has a mental illness and that it is the mental illness speaking and not him. I remind myself that when he is in a good place that he does not believe these things about me and what he thinks of me can change from one day to the next. So I keep myself at a safe distance emotionally.
I would suggest that when you do start to take the things your W says personally that you tell yourself the truth. The only way to combat lies is with truth. So if she says you are selfish, then your truth is to go through the things that you have done that are not selfish.
I'd also like to suggest that you work on using
Validation and
don't be invalidating . When your W says that she feels like the house is only yours she is not saying that to attack you. What she is really saying is that she feels separate and that she doesn't have a place. She feels alone and that she is scared of losing you.
To validate you might say something like, "I'm sorry that you are feeling so scared that I might leave you. I've felt worried about those things in the past before too and it's not an easy feeling. You are important to me and I want to be sure you feel like you have a place in this home. What would help you know that you are wanted here?" And just ask her questions, truly listening to what she is trying to tell you about her emotions. Don't discount what she is feeling or believes, even if it's not true, but not agree to things that are untrue either. Just show understanding, care, and that you are listening.
