Moving In, Extra Roommate?

I wouldn"t invite in a male either under these circumstances.

From what you have said so far, I do not consider the friends to be "in need".

I'm not able to live with my parents without significant strain :/ it makes me extremely depressed living at home with them.

I wasn't saying that my lack of experience didn't matter. I was trying to express that earlier I felt like my judgment was being diminished in validity if I somehow revealed that I was "very young".

My apologies, I assumed you were very young because you mentioned curfew. I take that back.

I wasn't seriously suggesting that your SO moves this girl in to help her out while you stay at your parents. I was trying to make a point how ridiculous it sounds. You have to be his priority, not this woman. She has a job and a boyfriend, and it's not your SO.

Even if she needs a roommate to help with housing costs she could look for roommates: other single people, not couples. Or she could rent a room in somebody's house. That's what my daughter did first year out of college. It's cheaper than renting your own apartment. Although she ended up with terrible landlord but that could happen anywhere.

This is so much of a NO for many reasons, I won't go into it. If you allow this to happen you'll be the one moving out eventually, trust me.

Yup. I'd hate to see OP having to move out. But that what's going to happen.

Nothing wrong with being selfish.

The idea and fear of being called selfish just seems like unneeded pressure from yourself and others who use that label to pressure you into something that could ultimately make you feel spite for your friend, and regret at yourself for having let it happen, possibly causing a fissure in your relationship.

Not any less of a person for trying to preserve your relationship. Doesn't make you look bad for doing so while others tend to expect you have 100% trust in everyone or else you're a bad person.

Your friend needs to find out something else for her living arrangements.

It's not selfish. It's common sense. Selfish would be if I refuse to drive my sick mother to the doctor because I want to watch a TV show. Not inviting a coworker to live in your place because coworker wants to save $500 by not renting her own place is called common sense.
