Please please don't marry this person believing that that will take you from misery to happiness. It will only lock you into the misery. What he is now is what he will always be, unless he actually recognised he's abusive and sought help. His control and surveillance and mistrust and humiliation of you is abusive, and is not the foundation for a partnership, let alone a married life together.

Please love and care for yourself enough to look at your situation honestly. There are people there who will help you, and we love you.
