How do you deal with disagreements, or your therapist showing less than ideal support for something you want to do.

In the beginning of the year due to roommate struggles I was out of a place to live and eventually went back to my moms, now I'm with my father. I don't hate my parents. But I've been wanting to live alone again. I don't want the trouble of another roommate and I hate living with either of my parents. My therapist doesn't support this. She believes it'll make it easier for me to be antisocial, despite already being antisocial. I'm not actively suicidal, nearly in my thirties, and am financially stable.
It was important for me to have her support, but as I prepare to move forward without it I question if I need/want any of her support at all. I feel like making this move without her behind me is the first step I take away from her completely.

So I am curious how did it affect others and their relationship with their therapist. Especially who it's not a frequent occurrence.
