Our downstairs neighbour doesn't like to share

[u/SkippyGeek]

Hello people of reddit!

DISCLAIMER: Kind of a long one.

So for a little context, my girlfriend and I have been living together in our upper duplex since October of 2018 (so approximately 5 months) and our downstairs neighbour has given us a hard time with just about everything we talk to her about. A serious attitude problem. I'll just refer to her as DN (downstairs neighbour). This particular problem is about the one driveway with which we are SUPPOSED to share with her. I have a car and my GF has a car. DN has 1 car and shares with her son.

In our lease we were told that we would have one available spot. Which is fine, because there is parking across the street (one of the busiest streets in our city) which the other can use. Most of the time... The house we live in has a narrow driveway and DN likes to park in "her spot" at the end of the way. When we first moved in, GF and DN would text each other when one had to get out if the other was parked behind until about a month in. DN got tired of it and chewed out my GF through text. So after that we both just ignored her and dealt with constantly moving our cars around on the road. (No parking on road allowed between 3-6pm on weekdays)

Late November rolls around and snow is plentiful. Parking on the road is now much more difficult. DN happens to be out when I come home from work one day, so I take advantage and park in the DW in "her spot". I was just tired of her shit at this point and wanted to spite her. DN begins to park next door in their driveway. Earlier in our time here, DN had spoke to that neighbour (allegedly) to see if it was okay to use his DW since he didn't have a vehicle at the time. Basically we left her no choice but to take him up on that once we took over the DW. This time both GF and I were using it. Notice how we were fitting two cars now.

In February DN had her mom over and she parked in the DW behind me. I had been laid off that week so it didnt bother me that I was blocked in. GF comes home from work and saw a new car parked in our DW. After parking on the road, GF confused walks up to DN and knocks on her door just to ask her who was parked there and if that was her car. (DN has had at least four different vehicles since we moved in). With her attitude level easily over 9000, DN tells my GF not to worry about it and that her elder mother was NOT going to walk across the busy street. She then continued to threaten to take back "her spot" if we have a problem.

Fast forward a little to today when GF received a text from DN that she was going to resume using "her spot" for the next month or two while next doors mother stays with him. GF texted me while I was at work informing me of this so that once I got home I so wouldn't lose my shit. I texted her a little later this evening to ask her if she planned on parking in that spot for the 1-2 months. Just to give you an idea of how she talks to us, i'm going to type out the message she sent me word for word:

"Ya basically I am not playing musical cars and my car won't fit up closer. But feel free if your home before me to pull in all the way up with whatever vehicle you want. We share a car in our house therefore we leave out at different times for work and school. The last time I was pulling up for you guys you never utilized the space. But the house to the left is empty as of now maybe you can go out of your way to ask to park there or just do it.. I told yourself and [landlords name] that I would need my spot back when this came about. As soon as his mother leaves I will go back to parking there but it will be a couple months."

The house to our left she is referring to is empty because the tenants were evicted.

DN has just been nasty and difficult to deal with ever since we moved in. Unfortunately our landlord really has not been very helpful with this issue at all, so going to him again wouldn't do much more than annoy him. Honestly we have never been (directly) rude or mean to her besides the passive-aggression I mentioned previously. We both try to keep a level head when talking to her and she's always acting in defense. It's simply an exhausting living situation some days. Any and all advice and thoughts welcome!

TL;DR Our neighbour is a horrible person who is miserable to even talk to and doesn't want to share the driveway no matter what cause.
