Is OTHER wrong in the post ? POST : Context: my dad died a year ago from drinking, his liver shit out on him and had too many other problems to get a transplant. My mom has a serious drinking issue. Not that she drinks too much, but any small amount can get her fucked up. I believe this is a result of one of her meds. My mom is also 56.

Anyway, we recently moved, and ever since then, shes been on every dating site talking to random dudes 24/7. In the past 6 months, shes probably gone on over 20 something dates, and shes likely banged 3 of those people. 

She recently met this one guy that I cannot fucking stand.

 Info on the guy: has a house in Maryland (we live in PA) with a boat. Has three DUIs (no more license) and lives with his mom in PA during the winter I guess. He smokes and drinks way too fucking much. He was a marine, but got kicked out or whatever for getting shot or something. We can call him Jim. 

So my mom meets this guy on plenty of fish. She ends up going down to this random fucking strangers house 2 hours away, for the weekend. I did not agree with this at all, but she didn't seem to give a fuck. The name she has this dudes name in her phone as "jim boat", and does not shut up about how he has a boat.

A couple weeks my mom invites this dude to our house one weekend, and they proceed to have loud fucking sex like I'm not even in the fucking house. After the dude leaves, my mom says hes not coming back, but she was full of shit because he came back new years eve. Meanwhile I went out with my friends. When I came back at one am, my mom was drunk off her ass bitching and whining about how the dude needed to leave and how I needed to call the cops because he wouldnt. Long story short, the dude leaves and my mom goes to bed. One other time, jim comes over at like 2am on a fucking weeknight and starts having loud sex with my mom. Keeping me up till 4am when I have work in the morning.
And to top it all off, I got back from babysitting last night at 12:30, and Jim is sleeping on the couch, bare fucking nude. 

I brought up my concerns with my mom but she doesnt listen, and says that her 18 year old son shouldn't be telling her how to live. I cant even come up with a good reason to be angry right now. AITA for being angry at my mom?
