I Refused to Let My Boyfriend Discipline My Child—He’s Not His Real Dad

I’ve been with my boyfriend Jake for nearly 4 years. He moved in early and became part of our lives—school runs, homework, bedtime. To my son Mark, he was basically a dad.
Last week, Mark lied about homework again. Jake grounded him. I stepped in, thinking it was too much, and in the heat of the moment I said, “You’re not his father.”
I regretted it instantly.
Jake snapped, said we were done, and left. I thought he just needed space.
Three days later, I found a letter he left for Mark:
“Your mom is right, I’m not your real dad. I tried to be… I love you like you’re mine, but that’s not enough.”
I broke down.
Now Mark is devastated. He keeps asking if it’s his fault and barely talks to me.
Even my mom told me the truth: I let Jake act like a parent when it suited me, then pushed him away when it didn’t.
I thought I was setting boundaries.
But now I’m wondering if I just hurt the one person who showed up for us—and confused my son in the process.
