I am moving in with my SO this month (August). It's been an ongoing discussion of when this would happen and we started talking about it at the start of the year. I am really happy that now it's finally happening. It took me a long time for me to convince my parents to let me move in with him, so it was by no means an easy milestone to hit.

His place has two bedrooms and one bathroom. Currently he's letting his brother-in-law stay in the extra room for a month while his place is being renovated. It's just a temporary situation before I move in, I'm totally chill with it.

Now I am presented with a choice. He has a coworker who is in a pretty rough financial situation and needs some help. She's been given some good job offers and one of them is in the city where my boyfriend lives. She was wondering if she accepts that job offer, would she be able to rent the extra room starting in October for ~3-5 months while she looks for another place? She has a cat.

My SO asked me if I would be okay with her renting the extra room. I honestly don't know if it is worth the extra rental income (my SO doesn't even want to charge her much because her difficult financial position) for this more complicated living situation. I understand that it would be doing her a HUGE favor. She is a very nice person, don't get me wrong, I do want to help her out. I'm just worried about potential roommate drama that will hurt friendships. We'll have three people sharing one bathroom--which is not impossible, just a bit of a hassle. The kitchen is also rather tiny, it would be physically impossible for us to all cook at the same time. And even though I like cats (I saw pictures of her cat and he looks absolutely adorable), I know it can be difficult cleaning up cat fur and taking care of a pet. Would the cat become restless being locked up in her room all day? We'd also only have three parking spots. One person has to do street parking every day.

I have all of these worries about this potential new roommate situation. And there is no definite timeline for how long she is staying. If things don't go well, I don't want this to put a strain on my relationship with my SO. What are your guys' thoughts/opinions on this. Do you think I should do the right thing and help out a needy friend? Or should I be selfish and say sorry but I wanted to have the place to just me and my SO?
