Is OTHER wrong in the post ? POST : My fiance and I have been dating for five years now and engaged for one. We recently bought a new home about six months ago after dealing with communal living for the previous four. I was under the impression that we'd be moving out together and alone to start our new chapter together, just us. I found out that this was not the case one month before we found a home. My fiance wanted her sister and my sister to move in. I said "no" and I was adamant. I was tired of communal living. We argued for a couple days. I did not "win" that argument. Next, I said "ok, we need to charge them a reasonable price for rent. I did not "win" that argument. They pay a nominal rent fee. "Then I have two rules:"

\* Do not park in the two foremost spots in the driveway (note this is a 3-car garage for four people).

\* Doors closed at 12am. I have two dogs that sleep with me and when they hear noises, the go off.

wo weeks ago, my fiance's sister came home at 12:18am- 10 minutes after I had fallen asleep. As my dogs went off, I was awoken with a surge of adrenaline. After realizing what I had happened, I was furious. I had effectively taken a power nap and was no longer tired. I texted my fiance and told her I'd get even. I texted her sister and went off on her for her lack of respect. I contemplated hooking up an alarm to my bluetooth speaker outside her sister's door but elected not to because of the collateral damage.

To be clear, I know my reaction to that situation makes me an asshole, but I'm wondering about the situation as a whole.

The next day, my fiance justified her sister's behavior with "Well she gets off at work at 9:40pm and still had to go to the gym". I pleaded my case and how that had no weight with me. She could have left the gym 15 mins early. For the next four days, my fiance and I didn't talk. On the fourth day she came to me and asked why I was upset and ignoring her. I was neither of these things. I felt defeated. I felt like i had been tricked from the start to buying this big ass house under the ruse that I could live comfortably. After talking it out, we ended on a good note. My fiance kind-of supported me but said that if her sister would be coming home late, she would accomadate. I did not like this at all. On day one everyone was good with it but now that it's not convenient to follow the rule, they don't. I shouldn't have to negotiate with a tenant in my home so I can get sleep. I go to sleep at 12am. That is more than fair and reasonable. I did not "win" this argument.

Long story short, my fiance came home last night at 12:18 from the gym and woke me up. The night was uneventful but the next morning I kept leaving the bedroom light on while I got ready just to be petty. I wanted her to feel what it felt like.

I know I didn't handle either circumstances well but as a whole, I need some perspective. I'm open to advice, or being told flat-out, I'm the asshole.
