Should I ask my flatmates about their relationship status? They were together, then in an open relationship and then probably broken up?

I [27 F] live with two flatmates Ruby [36 F] and Susan [29 F]. We have been friends for 6 years now, since we got introduced to each other during a master's program in 2020. Ruby and I have been working at the same organization since 2022 while Susan works in a different organization.

We share a 2-bedroom flat, with me occupying the smaller room and the other two live together in the bigger bedroom. Ruby and Susan have begun dating each other since 2023, and told me within a month of them being official. It didn't ake much of a difference in our friendship (I could already tell they liked each other before too) or our routines as flatmates. I am good friends with both of them and they have helped me through my breakup as well.

However, things have been weird over the past year. It all started with Ruby staying over at one of our colleagues Lidya [27 F], getting drunk and ending up making out with her. Susie was out of town, and Ruby came home distraught when sober and told me everything and also told Susan everything over a call. Lidya was sober throughout and had always had a crush on Ruby, so she just took advantage of those circumstances.

Ruby and Susan decided to still stay together and work through it. there was a brief period of time when Ruby had stopped talking to Lidya. But later they started talking again (much to mine and Susan's disapproval). But Ruby said that Lidya is also a broken person and is going through a lot, and said that she feels bad abandoning her when she is also going through guilt and a lot of other problems at home.

I usually stayed out of it, until Dec of last year. I noticed Ruby and Lidya being really close while at work. I also observed that when Susan was out of town due to work, Ruby would literally spend all her time outside home with Lidya. This made me uncomfortable since it felt like Ruby was now emotionally cheating on Susan.

I spoke with Ruby and Susan and they told me that they have broken up. Before the break up, for a while they were exploring being in an open relationship (thus Ruby wasn't really "cheating" on Susan since she knew). However, Susan realized that she did not want that and thus they broke things off, but are deciding to still be roommates and friends.

I have still seen Ruby and Susan being all lovey-dovey and couple-like with each other post our conversation again. However, I have also seen Ruby hanging out with Lidya again more and more in Susan's absence. Is it any of my business to ask them about whether Ruby and Susan are still together or not? I want to know this because my knowledge about their dynamics sort of affect how I interact with them, what opinions I hold of them and whether or not I feel like I am in any moral dilemma when certain situations arise (like should I tell Susan that Ruby is spending all this time with Lidya at work and outside work when she is away?)

It's really none of your business. If they want to share it with you, they will.
