My dad passed when I was 15. Him and my mom weren't all that close by that time, so while it hit me hard, she wasn't as fazed as you'd expect. I joined the military when I was 17, and in my first year out of the house my mom remarried. I never really vibed with him, just had different personalities and such.
He would often make snide remarks and tell me to, "man up," about any inconvenience I'd be upset about. This led to spats between us, and I was often just as at fault as he was for these disagreements, though it never got too serious.
I got medically discharged after a little under 5 years and my mom and him said they'd be happy to have me back in the house. I told them it'd be brief, just until I got on my feet and got a job, and even offered to pay rent, to which they declined. About 3 days in to being back home my stepdad when alone with me, asked what he thought a fair rent would be.
