So this has not started out the way it should. Two nights straight W has come home at 11 pm and after 12am lastnight each time waking me up when u have to be up at 330 am for my school. So finally lastnight night after she pulled in I went down and sat on the stairs. When she tried to sneak in the front door I was sitting there. I said, "W I need you to know this is not a hotel where you came and go when you want, she said I can do what ever I want. My reply was "if you think you can do whatever you want then I don't think this situation is going to work this is still my house." she states "it's our house and if it wasnt for me you wouldn't have it either. I said you gave up the house when you left, and she actually turned to me and said I left not her. I realized it was going no where fast so I just said you nred to try and think about the other people you are affecting by your actions. And went to bed. I was so angry only got 3.5 hours of sleep and that's not good for my master fitness course where in exhausted daily. So how do I approach this thing, cause it is obvious she is not staying at my house to spend time with our friend. She is actually using it becuase she is out all night with OM doing acrobatics. Which makes zero sense why she doesn't stay with him. Ill admit I was super angry after being woke up two days straight. And I'm a super light sleeper and once up I struggle to sleep again.
