C’mon, grow up. You cannot go on like a child that ‘I want means I want’! Accept that he is married with one son. You might be loving him unconditionally but he does not seem to be involved with same intensity. I do not think he will leave his wife for you. If he has this much of courage and love for you then he would have not married in a first place. And remember, you found out that he has a son but he has not told you! Where is a love? Whatever he might be talking about love for you, his actions are not collaborating.
