We keep fighting

My partner and I have been fighting sooo much lately and it’s becoming scary for both of us. I’m hanging onto the fact though, that it is potentially because we live with my parents and have for 2 years now. Maybe we just need to get our own space? We pretty much live in one anothers pockets because we’re both not comfortable to move around my parents home, so we stay in our room. But in turn there’s no breathing room so when someone is in a slight mood, the other sees it straight away and right now everything comes across as an attack for the other. What are your thoughts?
