I just found out my roommate is a liar and her use of the AC has caused the utilities bill to skyrocket - I do not think we are compatible. What should I do?
I have lived with my roommate for about a year now. We became good friends but I recently asked her about a series of lies she told me and instead of telling the truth, she doubled down on the lies and told stories that were far-fetched and untrue.
I approached her and asked her about these things and did not label her as a liar but also made it clear I didn’t buy her story. Since this conversation, she’s been extremely passive aggressive towards me.
She also stomps around, smashes dishes together, slams drawers and doors, and vacuums at all hours.
She has also programmed the AC to run between 67-68. She lives downstairs, where it’s about 5 degrees cooler. Before I found out about the lies, I told her it was too cold for me, we agreed on 70, but she continued setting it to 68. I am physically extremely uncomfortable.
We live in a dry climate where it drops to the 50s at night and days are in the 80s. She also has the AC running during peak hours and our utilities have skyrocketed as a result.
I feel like an asshole, but I reprogrammed the thermostat to be 74, which is comfortable for me. We are surrounded by large trees which keep the house cool and if it were up to me, I wouldn’t use it at all. The thermostat is based on the temperature upstairs, so it should stay around 68 downstairs, where her area is.
I was ignoring a lot - the thermostat, the noise, but I’m at my wits end.
The thermostat issue, in addition to her lies, petty and negative behavior, and disregard for the planet / money, I don’t think we are compatible as friends. We are on a lease together and I am trying to make it work as roommates but I don’t feel comfortable in my own house anymore. I lived there first, know the neighbors, have a garden, and own most of the furniture. I am tempted to contact the landlord but I don’t want to go there if I don’t have to.
