I think you're wise to protect your daughter from any negativity. We're in touch with my Son's paternal family, so I can't set the narrative, but I do remind them that I don't want anything negative said about his biological father in front of him. You may find it helps you to let a close friend in and confide in them, giving you a way of talking about what's happened. Alternatively, I'd recommend seeing a counsellor - this really helped me. 🫶🏼
I'm a solo mum by choice, my about to turn 12 and 19m old are both donor conceived (same donor) and when people asked who the dad was I'd just reply there wasn't one, they don't need nor are they entitled to anything more than that
To be honest it’s nobody’s business but yours and if people leave you because of this it says so much about them! ♥️♥️
