“All names in this story are fictional.”
Let’s name the people in this story: me, my girlfriend, my girlfriend’s friend (let’s call her Nancy), and Nancy’s girlfriend (let’s call her Lisa). Yes, Lisa and Nancy are lesbians, and here’s the story.

My girlfriend has been friends with Nancy since early childhood. Later, Nancy met Lisa, and the three of them stayed close friends for about five years. But here’s the catch: Lisa is in a relationship with Nancy, yet she’s in love with my girlfriend. She admitted it to her multiple times, gave her gifts, and kept showing those feelings even while dating Nancy and even now.

During the last six months, my girlfriend started distancing herself from Nancy because Nancy changed a lot and became very toxic and mean. A few days ago, Nancy came back from vacation. Me, my girlfriend, and Nancy all work at the same place. Nancy met my girlfriend and said: “Lisa and I broke up because of a girl she’s deeply in love with.”
P.S. Nancy knows that Lisa is in love with my girlfriend.

But there’s one thing that doesn’t add up. Lisa and Nancy used to text and talk on the phone practically 24/7 while they were together. According to their story, they broke up, but I noticed that Nancy still texts Lisa constantly and talks to her on the phone all the time.

Today my girlfriend and Nancy went to a bar, and during their conversation Nancy seemed very sincere (at least according to my girlfriend) when she said that they really broke up and only talk about the apartment they live in together, since Lisa is currently in another country. But it still feels strange to me that they spend so much time on the phone. What can people possibly talk about for 6 or more hours every day just because of an apartment?

Nancy also said that her mom thinks all of this is temporary and that I’m just “playing around” with my girlfriend and that our relationship is nothing serious.

P.S. My mom actually loves my girlfriend, is very happy about our relationship, and also gets along very well with Nancy and Lisa. She has known them longer than I have, and she works with us too.

So now my girlfriend and I have a theory that Nancy and Lisa might be trying to break us up for some reason.

And here’s the main question: what should we do? How can we expose the truth and understand what they really want? I’d appreciate any advice or opinions.
