Falling for someone while on a relationship ?

Hello all!

I've "recently" been diagnosed with BPD (it as been 3 months now) and i feel like it helps me understand the way i think and act a lot better. For the first time in my life, i dont feel like im "weird" ! Or at least not as much as before...

But there is something that keeps me awake at night these days ; is it possible that the BPD is making me "fall in love" with other people very easily? EVEN if im already in a relationship ?

Dont get me wrong, i do not cheat on my partner ! But now that im diagnosed i can clearly see a patern in all my love life. I usually fall HARD in love with someone and with time i get kind of "bored". I know it seams very mean and rude but its something i cannot control. And right now im in a very healthy realtionship with a guy that helps me everyday ! It has been 3 years, a miracle for me.
But ive started a new job, and there is this one guy... I wouldnt say i've fallen already, but i'm already attracted to him. I do not wish to end my relationship because im pretty sure all those feeling will pass and all.. But i feel very conflicted none the least.

So, long story short : is it possible this is because of the BPD?

Also, i dont know if it is important or not but i am asexual. So when this happen it is very emontions based.

(I am very sorry if my sentences feel a bit weird, english is not my native language !)

Im not a BPD, but my ex was and see fell in love with me while being in a 3 year relationship. She cheated on him with me, then through him away like a piece of trash. It seems that yes, it can be a thing with BPD. Most BPD's I've met or stories Ive read are notorious for falling for others while being in a relationship. Its so wrong as the damage she did to her ex and me seems at times impossible to get over.

I am married and I have a pattern of doing this.

I found out in my case it's limerence. Look it up if you haven't heard it.

I think that people with BPD are more suspectible to limerence. They have many of the same causes.

I know what you mean... I'm newly diagnosed with mixed PD (BPD being in that wonderful mix )

I'm in a four year relationsship with an amazing guy who loves me and does everything to help me. I love him, I do, but I get attracted to other people (Since i'm bi, this being both men and women...). And with attracted I mean both physically and emotionally... I imagine my life with these other people, and suddenly that seems so much more right. I really can't control it. I've never cheated, and I don't want to either, but my head is somewhat always convincing me that the grass is greener on the other side, and that another person would be more "right" for me....

is it an open relationship?
