I love my fiance and his son to pieces. Son lives with us during the week and 1 weekend a month (frequently more as ex often cancels). Ex and his ex-wife loathe each other for reasons going back to the custody battle. She lost full-time custody 8 years and and, despite lip service on occasion, really doesn't want full custody. The son has a learning disability that we're dealing with and our biggest issues are him not doing homework, a refusal to eat anything healthy, and terrible hygiene. Basically, he's a normal 15 year old boy. I love him but occasionally wish he would disappear into his room for the next 3 years!
We all live together and I'm the person who tag-teams parenting duties with his dad on things like parent-teacher conferences, doctor's appointments, and the miserable everyday battle over homework and vegetables.
FI's out of town for work this week so future stepson (FSS?) is with me (not the first time this has happened but the first time since his ex resurfaced after going MIA for months). Ex wife found out about this when I went to pick him up yesterday and threw an epic shit fit complete with threats of police, custody battles, etc. FI screwed up by not telling her in advance (not that she wanted to have him stay with her, of course) and she handled it equally badly. I defused the situation and gave her my contact info.
Funny enough, FSS called her last night whining that I gave him food that made him sick. He ate 3/4 of a box of a high fiber cereal it was like Cheerio's. He was in agony from to much fiber but still ate the dinner I made (I found the empty cereal box later). When his mom texted me for an update, I gave her the real story and heard him getting responding to her phone call moments later.
FSS knows my approach: I don't want to replace his mom and think that the more people who love a kid, the better.
I feel like I did a pretty good job of handling my first serious step-mom situation but want to ask the crowd: any recommendations for being a kick-ass step mom?
