My mum remarried when I was 4, divorced when I was 12, met someone, split up when I was 22 and recently married for the 3rd time.I have a brilliant step-dad who has more than made up for the crappy job my biological father did. He’s been in my life for longer too. I’m lucky in that respect.
I would never keep my boys from seeing their dad if we ever divorced. There’s definitely a pattern with R though, as mentioned before.
