AITA for needing space from my mother

I (F25) and my boyfriend (M26) have been living together for around a year and a half. Before, I was living with my mother and honestly really needed space from her. I have had mental health related problems in the past and she threatened to kick me out when I was already struggling multiples times. Now, she writes me quite often long paragraphs about the fact we don’t have the relationship she would’ve wanted and that I don’t come to visit as often as I should in her opinion.

AITA for needing space from her?
