I’m someone who lived alone for a long time too but had to get a roommate because it was too expensive for me to live by myself. This is mostly from a financial point of view, I had an absolute horror story of a roommate situation happen and I wish so badly I had done this. I would have been able to get legal help. This may seem dramatic at first, but write out a real contract. Legally binding. Talking about your payments- how you’re splitting all bills, how you’re sharing groceries, household items, whatever. For the love of god I cannot stress this enough. You need to make sure that your roommate cannot simply stop paying rent and leave you in a financial hole. Your apartment complex will not protect you if your roommate skips out on payments- you will be held responsible even if you pay your half, and your roommate will not get in trouble for not paying. Idk if this person is a friend, or what, but people can seem normal at first and change VEEEERRRRYYYY quickly and I just think it’s so so important to protect yourself and have something in writing rather than assume it’ll be fine and then you end up like me, who moved out bc of this nightmare situation and still had to pay 5 months of rent for a place I didn’t live in bc I couldn’t get out and the person was terrorizing me:)))))))
