Breakup?

anyone else decide they wanted to go through this peri transition alone instead of with their partner? i love my boyfriend of 3 years, but even when he’s doing chores and splitting bills and being super wonderful all around, i just want to be alone. i don’t want the expectation of connection, i don’t want to shoulder anyone else’s needs. i just want to be alone and think about my life and make it through this transition. i need all of my energy for me. i’ve been thinking this for the past year, but just thought i’d get over it, that it was peri mood swings related. but i kind of think it’s just who i am. he’s the first guy i’ve lived with for more than a month (it’s been 3 years now) and while i can do it, i really prefer my own space. i guess i’m just venting and looking for other people’s personal experiences rather than direct advice. thanks all <3
