What do you envisage to be a fantastic relationship?
One of equality? One where you both minx together as one? One where you share your day with each other ? One where you laugh and joke together as best friends?
Based on what you have written, if you were to "try" to tell her that you don't wish to tell her your every move, right down to taking a shower and that you wish for her to join in with you and your friends instead of wanting 100% of your time alone, do you think that she would take that ? I don't. She is who she is, you are who you are, she is not the only lady in the World and as you've said it's toxic and you are drowning.
She would not feel betrayed or if she did, she would say " not another one' in other words "no one " would put up with that, that's not a relationship it does not constitute a relationship .
She will not understand you as she has rules abide or go.
I think you can do better don't you?
You don't need this and annoying is an understatement it's controlling.
Just tell her that you aren't able to be in this type of relationship it's not you, see if she offers ideas somehow I don't think she will.
