I think your actions were appropriate. You can love someone, and forgive them, but not trust them.
My first wife was very similar to your husband. In my case, and I am not at all saying what you should do, I believed that divorce was necessary to protect my children. Eventually the courts believed me that she is a threat to them, because she is legally prohibited from any contact with the children (and that order was from a sympathetic liberal judge).
However, in looking back I regret that I did not consider what God's will was in my marriage. So I encourage you to pray for strength and direction in this mess.
I will also pray for you.
May the God of endurance and encouragement grant you to live in such harmony with one another, in accord with Christ Jesus, that together you may with one voice glorify the God and Father of our Lord Jesus Christ.
