Hi Antlen,
This is actually really common for BPDs. I find it to be a fine balance. I don't say 'I love you' a million times to my husband in a day because he starts to be suspicious... .I also don't avoid saying it more than once just because I might trigger him.
I used to believe that if I managed 'things' in our relationship well enough that I would someday find a place where I wouldn't trigger him. Now I understand that his triggers are his responsibility. Not matter how much I would walk on eggshells - if he felt like going off of the rails then he would do it. I have a long history with my husband and things had started to go SOUTH badly. Years of placating his every whim + some outside stressors led us to a very bad place and I realized that I needed to change things for us.
I started with the lessons ----> (on the right)
If you haven't started taking a look at those - I highly recommend them. At a minimum they have saved my sanity. Ultimately they may save my marriage.
A good place to start is the video about 'before you can make things better... .you have to stop making them worse.'
We're really, really happy you are here.
It's hard but as I'm in this for the long term, I've got to show her i respect her decisions
This shows a lot of wisdom on your part!
Welcome again.
