A ventriloquist can almost give life to his puppet/dummy - make him charming and lots of fun. In the end, the dummy always has a wooden heart and can feel nothing.
If he did
agree or was coerced into this relationship, you and your child would never feel loved. Your life will feel empty and unfulfilled, and he will always be unhappy.
If he was different it would be a good idea. He is not, however, and I don't believe this will work.
If his father was a strict Peruvian military office then he probably never had a role model to teach him to be a compassionate father but rather to be harsh and formal.
He gives no indication that he is a dangerous psychopath or that you will have to worry about being at risk. He is not likely to be dangerous - just emotionally unavailable. That is the key ingredient for an unhappy life.
The best actor in the world cannot create the feeling of being authentically loved.
From what you say I am convinced that it is in your best interest to let this dream fade slowly into the past and move forward with your life.
I shall keep you in my prayers for success. fulfillment, and happiness for you and your child.
