Title slightly for click bait.
Yes, I had an affair. So did my ex - he cheated on me with many women over the years but accepts no responsibility as he didn’t leave me for any of them. He was also a functioning alcoholic and I basically brought up the kids on my own when babies and toddlers as he wasn’t interested until they were older and compliant.
I ended our marriage when I met someone and wanted to make a relationship with them. I did have an affair for a time. I stayed co parenting under the same roof with my ex for some time (extended due to pandemic) and did a nesting arrangement for a year (taking turns to spend time out of the family home to stay in a flat). We finally moved into two separate properties last summer and have the kids week on week off.
They are KS2/teens.
I’ve now been with my affair partner coming up to nearly 4 years. It’s a long term relationship but no plans to move in for various logistical reasons (he looks after his kid full time in another city). But, I still haven’t introduced him to my kids as I am very scared on my ex’s temper and what is a fragile coparenting relationship will flip and mean he takes a lot of anger out on the kids. He already gives my eldest teen guilt trips when she wants to spend time with her friends and boyfriend instead of him and her younger siblings. My guilt at being the one who ended the relationship in this way is also talking loud. I know I didn’t do right, but I would start to like to have some time with my partner and kids. I know the advice will be “just tell the ex” but how, and how do I manage his anger and the kickback on my kids. He loses his temper a lot.
