Please give me advice ladies !!

So basically I want to find my real father, I am 25 years old and would like to contact him... I honestly don’t want nothing from him I have my own life now ... I would just like some answer’s and to find out why he didn’t want me ..... I’m scared he will not want anything to do with me

I know he has another family now and don’t want to come between them... I don’t even know If they know about me ....

My husband don’t want me to contact him in case of rejection.... but other than my husbands family I don’t have a family

Im really stuck in what to do and I need some advice please ....... I don’t want to upset anyone or cause a rift between anyone
