Save the last category (escalation), the boy I dated from age 17-21 ticked every single box in that Red Flags article. Every single one. For four years.
As a teenager, I was confident enough to sing solos in front of an audience and perform in the school drama club. I played two team sports. My father taught me how to throw a decent punch and defend myself physically. I made my school's Honor Roll and kept good grades in advanced track classes. I was taller and physically stronger than several boys in my school. My parents are still married and have a healthy, respectful relationship. My mother and father both have hobbies and interests of their own, separate from each other. Mom, in particular, has always had a life of her own outwith my father, my brother and me; and my father has always supported and encouraged this.
And yet, at age 17, I believed my boyfriend when he said I was a bad girlfriend for going out with my girlfriends to the mall and not inviting him. At age 18, I believed my boyfriend when he told me I should be "putting him first" and should prefer to sleep in his college dorm room, rather than my own. At age 19, I believed him when he said the girls I tried to make friends with were dumb, and were trying to interfere with our relationship. At age 20, when I finally broke up with him, I believed him when he said I'd never find anyone as sexually compatible with me as he was. And so I kept seeing him and having sex with him for another year, at age 21.
Controlling relationships really can happen to anyone. Even if you think they are bold, confident and strong. Even if you think you've set a fine example. Even if you think it couldn't possible happen to your daughter or son, because surely they are far too intelligent to fall for that.
Emotional maturity does not always arrive when it should. So I will absolutely tell my stepdaughter over and over again what those red flags are, and what she should expect from a decent relationship. I will spell it out. And I'll be spelling it out long before dating and the pressure to have a boyfriend is on her mind!
