Ex-husband not allowing wife to move on

Salaams muft,six years ago my husband gave me 3 talaaqs at once,no family members did anything to separate me and my husband because I was told taaaq was valid,from the time of talaaq I am still living with my husband,I have asked my two adult sons and my brothers for assistance in helping me to speak to my husband to do the right thing and allow me to move on with a man that I have ,I am not geting any assistance because my kids and my family think its wrong what I am doing.please mufti could you advise me? I have not sat for iddat because I did not know.by the way the new man in my life is white and wants to convert into islam,I am 51yrs old and very troubled.jazakalla
