You seem to be struggling so hard with this issue -- your profile page says you are 20 years old -- the same age my daughter was, when she moved out and into a place with her best friend. She had been talking about it for a few months, so, maybe that was her way of preparing me for the change. I would have been quite happy if she had chosen to stay home a little longer -- she was my last child to move out -- empty-nest syndrome was looming!!

It was her life -- her decision -- all I wanted, as does any parent, is for her to be happy. That was 13 years ago

It is your life -- it should be your decision -- you are feeling the stress of your parents' relationship, and it is not healthy for you

If moving out of state is financially possible for you, I would bet that you would love to be in a place of your own, on campus -- as a parent, I would certainly understand and support my adult child's wanting to do this.
