Not even just a wet blanket. If you read through the comments he is also verbally abusive, but still a giant pussy. I dated a girl like the OP. I was fucked in the head at the time in the midst of a 4 year battle with depression. She had no father growing up and a mother addicted to me  1000  th for most of her childhood. When I went off to jail for shit related to my insanity and depression my gf hooked up with an exact replica of OPs beta bitch bf. I'm not one to talk shit, I was a beta myself. In a lot of ways I still am, but I'm actively working on, you know, fucking speaking my mind and not taking other people's shit anymore. Anyways, my story gets interesting in that I was enough of a bitch myself to get out of jail and go right back into a relationship with my gf. Because we were locked into an apartment lease for the next 9 months. So it is me, gf, and new dude in a hilarious three wheeled relationship. And. She. Never. Fucked. Him. Once. At the time I felt really bad for the dude. This was supposed to be an open relationship and I was the only one getting any. It didn't feel "right". But the dude was just a right asshole verbally. He screamed and yelled at her all the time over petty shit while doing fuck all but working, playing video games when he wasn't at work, or smoking weed. Me, being the bitch I was, didn't do anything about it because it was between them. He eventually left because the relationship was a shit deal for him. Basically she used him for money and a ride around town while fucking me. He didn't ask to be cucked, but that was the reality. Good on him at least for leaving. He's still a shit human though. I'm willing to bet OPs bf is pussy enough that she could cuck him and he wouldn't be able to verbalize opposition. He'd just ratchet up his passive aggressive verbal abuse in response. Literal emotional child. It learned how to work a job but stopped acquiring any more responsibility past that development.
