Need opinions

So my soon to be husband freaked out because I stayed friends with my ex that I have known since I was 13 we only dated a month and broke up but stayed friends well since my hubby was insecure I stopped being his friend im frustrated because he was all insecure and jelious over me yet he is all buddy buddy with several females he used to have relations with one girl he used to mess with he swears is like his best friend but he gets mad when I get jelious and he shuts down I dont understand how that is fair he even had one girl he used to be engaged to saying she loved and missed him she is in another country but it still bothers me am I wrong?
