Hi anePB,

You have come to the right place to start to learn more about BPD and the tools you will need to navigate. It's not an overnight solution, as it sounds as though things have escalated in your household.
My wife and I also drink more than we should and everytime she gets drunk I end up getting yelled at, accused of nothing and physically abused and she never can tell me the next day why she acted that way.
Alcohol use is common among pwBPD, as I believe they seek to feel better, a way of self medicating. The problem is that they lose the ability for self control, and spiral. She is either having a blackout of splitting so much that she doesn't remember what she says or does. They are both scary situations.
Your children are of upmost importance. Do you feel that they are safe? Has she considered going to therapy before?
You mentioned that she seems to act up prior to leaving on a trip, or you leaving on a trip. Do you notice that she is under some type of stress? Money issues can always be a big stress point.
My husband is also jealous of me, and like you avoid talking or messaging the opposite sex. It is all unfounded, but to him it's all real. And it's doubly hard to be blamed for everything that goes wrong.
Learn as much as you can about BPD and arm yourself so that you can take care of yourself and your kids.
With Kind regards.
