ACoAs often wonder if their behavior is "normal." It's one of the defining characteristics of adults from toxic families.

That being said, I think what you did was very healthy. You saw that your "friend" was lying to you - and it sounds like you don't deem this acceptable. You were aware that his girlfriend is a bit on the unstable side, or at the very least is toxic to you in her behaviors. You were aware that this social triangle was not in your best interest. You then made a boundary about what you deemed acceptable, and informed them that they were outside this boundary. Then you defended your boundary by refusing to be involved in this triangle anymore.

So you were in a toxic place, and you chose to get out of it. That doesn't sound wrong to me at all. It sounds very very healthy.
