This is my roommate, not family, but close enough. I can't vent on Facebook, because she'll see it.
I'm in my mid 30s, professional. She's early 20s, premed, from NYC. We're in a suburban area of Albany. I own the house. She has the upstairs and I the downstairs. There is a staircase but no door separating us, and we share the downstairs kitchen. She has a small Pullman kitchen, separate bath, bedroom, and living space upstairs.
My previous two roommates (both now graduated) have never had noise problems. I can hear her TV as loud as mine when in in the living room. She plays music loud enough to hear the lyrics downstairs too. I know it's her and not me because I've never had a problem before. Things are that loud until midnight or 1 AM, and start again just as loud at 7. This messes with my sleep schedule, obviously.
She has different guys here every weekend and they stay from Friday through Monday. I don't mind overnight guests but they overstay their welcome. This isn't a flop house. Also, her guests arrive at odd hours (like just now at 2 AM, and she turned on all the outside lights that shine into my bedroom to let them in, waking me up, and then "forgot" to turn them off again.) Lastly, the guest's car is parked behind mine in the driveway, blocking me in until who knows when tomorrow. Or, rather, today. This has happened several times before. She does not have a parking space in my driveway, as she has no car.
I have told her about the noise multiple times, but not the guest situation. I don't want to henpeck, since I theoretically don't mind if she has people over, but this feels like it's starting to be rude, if it hasn't been already. She's a nice person otherwise, and I don't want to drive her away, especially as she's paying half of the mortgage with her rent, but I don't know what to do.
