OP here (I made this account after submitting this, I didn't think it would get accepted.) Basically after her constantly cheating on him, claiming he was abusive despite her being physically abusive to him, and lying all the time, he'd had enough and threw her out since she decided to keep going back and forth between him and another guy. (And she had the balls to claim she was pregnant with his kid, even though she was on birth control). She'd left a ton of her stuff, and even though he'd texted her/called her to tell her that if she didn't pick it up he'd throw it all out, she never replied or made any indication that she was going to pick it up. Suddenly she thinks it's a good idea to come at over at random times, climb the side of the house, and try to get in the window, saying she needs to get in the garage and get some old stuff. (I have no idea why, because there's literally nothing in there that is worth this much trouble.) The reason why she climbs the side of the house is because my boyfriend and I both live with his dad by paying rent and just living upstairs. His dad doesn't want her around the house anymore because of their previous arguments, which made the environment depressing, and the fact that she put a hole in the wall before. This was the last straw, she hadn't come around for months and after shooing her away this time, we're going to take legal action if it happens again. Neither of us knew how to properly react since it was so early in the morning that we just wanted to get some sleep. (I couldn't manage to fall asleep until at least 9AM)

Hey guys! Op here. I'm pleasantly surprised this got published! I guess I should have explained the whole situation a lot better. It was not my idea to snoop, as I was making them dinner, and I heard doors opening and closing. I went to investigate, praying it wasn't a break in. Instead, I found the kids looking through the closets. I asked them to stop, sit down, and watch tv while I continued cooking. I watched them go back to the main room by the kitchen where I was, but I guess they snuck back out. When I checked on them again, they were looking at, you guessed it, sex toys.

Hey guys, OP here, really glad that this was my first FML to be published :) I guess I should fill in the plot holes here, yes the house was dark, she came through my porch door and through the dining room, which the creaking in the floor (as my dining room floor is known to be obnoxiously creaky) is what alerted me to think of an intruder. I was in my room on the second floor and there is a wall blocking my vision of the dining room once I get down, so when I got down I peeked the corner and just went at it at the human-ish form. Ended up fracturing one of her ribs, would have been worse if my boyfriend was home and he was the one doing the hitting. Family thinks I'm responsible because "I should have recognized it was my sister" but sorry if I hear someone breaking into my house I'm not going to sit down and have a nice chat and tea before deciding to do something. My family was in on it, and they're still trying to get me to pay, but I'm not budging on the fact that I was just trying to defend myself. Hope I explained it pretty well, thanks to everyone who helped get this published :)
