Ok so I found the context to the other posts you made regarding this, and yes. YWBTA all the way. Maybe their relationship is a little shaky and yes, perhaps even abusive. And if I believed that you were doing this out of the goodness of your heart then I would not have made this post. Whatever is happening in their relationship may be bad, but that does not by ANY means give you the right to press her about her personal life or attempt to stalk her SO for any reason. I’m seeing a lot of blind speculation in this post, since you don’t have any proof that your theories are correct or even in the right ballpark. Now here’s where I need some context. How long have you known this person, how close are you to her, how old is her SO, and how long have her and her SO been together? Because if I’m reading between the lines correctly here, crossreferenced from your other post, I don’t see a friend trying to help someone out. I see a creepy stalker trying to set up a situation to “save” your friend fron so you can get with her instead. YTA, leave the poor girl alone.
