Sharon asked 4 years ago

My husband took a second wife in Ghana over a year ago I just found out. There is a baby that is 6 months old from the marriage I live in the US with the husband and he lied throughout the process even when asked cause I had a thought and some evidence showed up he still lied repeatedly 
I know he didn’t need my permission but I’m not emotionally prepared for all of this at once 
He always said he didn’t want a second wife and we discussed if he did he would advise me 
What advice do you have
