Useless

Hello. Here's my problem. My step dad is the most useless man alive, He abuses my mom (mentally and financially) by not contributing to the household nor tending to her needs. My mom has to work 2 jobs to support all of us. Everyday I can tell she is sad and very unhappy. All he does is sit around the house morning till night, watching tv, smoking cigs like a steam engine and not to mention watching porn all day everyday while my mom is out of the house either working or going uptown. Its driving me insane to see how my mom is being treated. She has caught him before using webcams to chat with other women online. He stopped for a while but now does it again constantly. I can't have friends over because as soon as u walk in u can hear him pull up his pants and the sound of his belt buckle clanging is a dead give away. Its disgusting and incredibly embarrassing. He was kicked out for a while before the start of the new yr but for some reason My mom let him back into the house. I told my mom I would help pay bills, groceries and what ever else that needs to be taken care of. I could care less about me being happy, I just want my mom to happy. My stepdad always complains about his back and legs hurting after ANY form of physical activity! No shit! Maybe if he didnt sit on his ass all day and jerk off he wouldn't be like that. I can't play games on my PC or Xbox one because he is taking up all the bandwidth and its annoying! When my mom asks why the power bill is so high he blames me for playing games all day let alone its him jacking off all day. I found a USB stick with his dick pics and pics of another lady I had no idea whom was also naked, I never told my mom about it and that was 3 years ago. I tell my grandparents everything that happens around here and there as disgusted as I am. My grampa said if this continues hell will be raised and I hope it happens...my mom needs a wake up call and she sure isn't listening to me. Any advice to give in this ridiculous situation?

Your mother is a grown adult. As such, she should be capable of ditching any man she felt were more than not being an abusive parasite. Is she not? Or does he have other redeeming qualities you wouldn't know about, or ones that make life more convenient for your mum? In fact, if you thought long and hard about it, might he keep her too busy to get on with things that she should be getting on with but would rather not tackle? Have you not thought to ask your mum why she let him back in the house prior to the New Year? Is she aware about his porn/electricity guzzling habits? And what about her parents, are they not intervening in any way, like trying to talk to her about this inadequate relationship?
