You did the right thing by welcoming the child and befriending the ex. That choice protects the kids from adult drama and fixes a secret your husband created. But “kind” doesn’t have to mean “boundary-less.” Here’s how to keep this healthy and sustainable:
Separate the wins from the wound.
Win: Siblings get each other. You turned a potential rivalry into a bridge. Keep that.
Wound: Your husband lied for months and let his mom blame you. Don’t blend these. Celebrate the win and address the wound with consequences and structure.
Make your husband carry the load he created. He sets up a clear timeline of what happened, no gaps. He initiates a full correction with his mother: “I lied, not Shiloh.
I’m sorry. Going forward, talk to me about schedule changes.” He says it, not you. He handles all logistics with his ex by default (scheduling, pick-ups, changes).
You join for decisions that affect your home/kids. Create a 3-lane plan: Kids, Couple, Extended Family. Kids-first lane:
Keep the weekly sibling time, but put it on the calendar you can all see.
Add one neutral-space hangout per month (park, museum) where you and the ex both attend. This normalizes things and prevents secretive optics. Couple lane:
Install a “No More Surprises” rule: any new contact, change, or feeling-that-might-blow-up gets told to you within 24 hours.
Do a 30—30—30 rhythm for the next 3 months: 30-minute weekly logistics check, 30-minute monthly deeper talk about feelings/trust, 30-second “temperature check” after each visit (“Green/Yellow/Red, anything weird?”). Extended family lane (especially MIL):
After your husband’s apology to her, you offer a simple reset: “Happy to coordinate visits—please text [husband] for schedule.” Short, polite, boundaries intact. Set “Green/Yellow/Red” boundaries with the ex (write them down).
Green (automatic yes): exchanging kids’ updates, planning sibling hangouts, attending school events together without seating drama. Yellow (ask first): sleepovers, big holidays, social media posts of your kids, introducing new partners to the kids. Red (hard no): rehashing old romance with your husband, triangulating (“He told me X, don’t tell Shiloh”), surprise schedule changes.
Name the role you
won’t
play. You are a supportive adult, not the relationship fixer between your husband and his ex, and not the family scapegoat. If conversations drift to old couple issues, redirect: “That’s for you two to resolve; I’m here for kid logistics.”
Verdict on your choice:
You were right.
You protected kids from fallout and chose connection over ego. That’s the high road. Now lock in structure so your kindness isn’t exploited.
The headline is simple:
the kids gained a brother; you should gain a plan.
