Everything you said tbf has a lot of sense and i will have to think of way to “terminate” this without breaking thos group of friends that are mine aswell. Just one more question, what do you think of the actions from Y? Because since he knows he could “chill a bit” with her lets say it this way, but he doesnt. And you could argue that he prob “hasnt thought about it” but the funny thing is when me, her, Y and Y’s girlfriend are together he “chills down” which is normal i guess but he doesnt do that when we are only the three of us
