If neither partner has the option of separation, then there is nothing left but to overcome pride, jump over the shadows, meet the other and change himself, his demands, his behavior and his habits. No matter how you feel about it, because change and self-correction don't feel good at first. Our minds are such that they want to keep us in the comfort zone and find a hundred reasons why other people or circumstances should first change before you set yourself in motion. The reflex to flee is therefore greater because we are familiar with running away.
