I 16f live with my mom 39f who is around 6 or 7 months pregnant i think (and really showing), her boyfriend 35m and their kid who is 9 months. I hate my mom's boyfriend. He sits on his ass all day Tuesday-Friday and plays on his computer all day. He has 12 hour shifts sat-mon while my mom works 10 hour shifts tues-friday.

He watches their kid while she works, but he doesn't really watch him. When the kid was first born, my mom mainly took care of him. When she went back to work and when the baby was old enough to hold his bottle, he stopped holding him when feeding and would leave him in his swing for hours. I mean HOURS. When he was old enough to eat baby food, he wouldn't feed him baby food and would just feed him formula. He wouldn't do tummy time or help him learn to crawl even when the kid was behind in mile stones.

I know all this because my mom complains to me. Alot. There's a camera in the living room, and she sometimes looks to see if he's actually taking care of him when she's at work.

He also doesn't help clean. He's never helped clean or cook. Now that mom is pregnant again and we live together, it boggles my mind he doesn't help more.

My mom walks up and down the basement stairs to do laundry. She does bottles and dishes. She cleans the bathroom and vacuums.

Shes had a few talks with him. He'll help a little bit more for a couple of days then stop after a while.

I try to help. I usually do. Especially with taking care of my brother. When her boyfriend works, I'm with her the entire time to help.

But I'm not the babies father, and I'm not her boyfriend, so why the hell am I helping more than him😭

Recently, I snapped at him. A couple of days ago, Mom was about to go do laundry, and I told her she shouldn't do it.

I grabbed the basket (btw I do my own laundry) and went into their bedroom where her boyfriend was doing something on his computer, and I told him he needed to go do laundry.

Now, this guy acts like a really nice guy. I'm talking goofy, silly, really nice, and positive, which is why I think my mom has a hard time talking to him, but idgaf. He sort of paused for a minute and just went okay. He went to grab it, but I put it down and told him we actually needed to have a talk first.

I feel like this is where I may have crossed a line because I've always been taught to never talk to an adult like this and i dont know what possessed me to do this but I sort of leaned down in front of his face so we were making eye contact and asked him if he was a child.

My mom told me to knock it off and that it was none of my business and I shouldn't be talking to an adult like that and I told her that she made it my business every time she complained about this.

I asked him again, and he sort of laughed nervously and went, no? And I was like (paraphrased here) 'are you sure? Tell me why my mom, your girlfriend, who is 7 months pregnant with your child, is doing the majority of the chores? Tell me why you sit on your ass all day while she's taking care of you? Are you. A man-child?"

I was expecting to be yelled at, but I've never spoken like that to anyone before and I think it shocked them both? I basically told him that he needed to get his shit together because my mom was a wonderful woman and he should be greatful she ever decided to not only date him but carry his children TWICE especially so quickly after her first shitty pregnancy with my brother.

I told him she could do so much better than him. He needed to treat her better. I told him he was not only going to get his ass up to do laundry, but he was also going to finish dishes.

I told him that I was tired of watching my mom works her ass off and treat him like a king when he never reciprocates and treat her like the beautiful, hardworking woman that she is. I asked him if we were clear? Did he understand what i was saying? Did he know why i was saying this? He just sort of stared at me and didn't say anything, which was making me mad, and I told him to get up. My mom told me we needed to talk outside and when we were she told me I crossed a line and shouldn't have said that to him. That I was disrespectful and she never wanted to see me talk to him like that ever again.

I asked her where had her self respect gone? Which i regret saying but seriously she complains to me ALL THE TIME.  He's 35. He should know how to help clean and cook and help with a baby because this dude has a kid from a precious relationship. This isn't new to him. He's not stupid. He actively watches my mom struggle and doesn't help more.

He actually asked me a while back to help him fold his laundry because 'he didn't know how'.

Are you deadass right now? I never helped him and he left his shit on the couch.

She wanted me to apologize and I said no. I was not sorry. I meant everything I said.

Anyways it's been a couple of days since and her boyfriend has been avoiding me. Apparently mom had a talk with him, and he thinks that I'm right and he feels ashamed of himself. I really don't care about how he's feeling. i just want him to help her more and take better care of his kid.

I may be the asshole for how I spoke to him but I dont really care. Bro needed to hear the words because it was driving me nuts
