I just discovered my daughter from another marriage is a “biological incestbaby” to a brother I’d never seen before and well yeah

So like I’ve just discovered my daughter is an incest baby and I’m definitely not a pedo I did not know she existed before until I caught her having sex with her brother well I was a 19 year who got kicked out of his house and I met her and this happened and we got married but well I found out she moved away and moved on but I got the news my daughter is a incest baby, I did not plan to meet her at fifteen but well your supposed to be proud of her, she is wonderful but sexy but I did not mean to have sex with her before, she is not a baby to me anymore. I don’t know what to do but I would be happy if I could meet her.
