Hey Amsmav, welcome to the group

There's a lot of stress in your life and relationship right now, so it's good that you felt like you could reach out for more support.
I hear you worrying about whether you're "the cause" of the distance between you and her. Would you say that right now (short term), the distance between you two during her current depressive episode is your main concern?
And I read that there hasn't been talk of couples counseling lately. Are you open to counseling? Is she?
Adding alcoholism to the mix with a PD is a lot to handle. Does she recognize that her alcoholism is a problem?
...
Lots of questions from me, I know, just getting a better idea of what you're facing.
I do want to note that I did see your questions in there! Each question deserves a good full answer, and in a way, they all kind of tie together in the question of "how do I have a relationship with a pwBPD and still stay healthy myself"? One place to start is checking out our articles on
Saving a relationship, and another is our
Tools and Skills Workshops, especially
The Do's and Don'ts in a BPD Relationship.
You guys didn't get to where you are overnight, so it may take some time, but it's possible to make changes in your own life and your own relational style that can help make the relationship "less worse".
Keep us posted on how the last few days have been, and again, welcome;
