I think they are required.

When I came into the picture my ex was going through a break up. I thought she had gone through it... .I had no idea the other person was still clinging to hope... .
because she was letting them believe there was some.
What I didn't know is my ex was already in contact with another ex and working them over. About a year into our relationship I was left for this person... .for two weeks. She came back when she realized there was no way she was going to move three states away... .so she had a nice vacation while I sat alone tormented.
I will tell you this. When I called out my ex she was honest about things. Like when we were fighting and she was texting someone. Later, after dumping me for this person... .
and coming back. She admitted she had been confiding in this person about our issues and she knew it was wrong.
When I read what I have written above it makes me ill. Now removed from this for a few years I see how crazy this was and I contributed to it by allowing myself to be treated poorly. This is why I think NC is so helpful in healing... .it lets you take a good hard look at what happened and why.
But back to your question... .BPD's don't have a solid identity, they rely on source (Significant Others) for that and they mirror you. You might have noticed your BPD didn't have any real friends or interests but seemed very interested in your life, and that's the draw, we all want someone interested in us, knowing us, our likes and dislikes. Unfortunately in these types of unions that allows us to be manipulated down the road if we aren't aware of what is happening. That's how I ended up on these boards, learning all I could about this dreadful disorder I had no idea existed.
