One of the good things about the relationship i have with my partner that i live with is that we can both sit there doing our own thing and be perfectly fine.
If you cant do your own thing in a relationship, get out. Seriously. its a huge red flag if they want to do literally everything with you and wont let you have your own life. I never realized how toxic it was until i lived with with this person and saw how healthy it was to have my own space.
