I think your gut is telling you something is off about this lie and how he reacted to you when you got upset that he lied to you. A red flag is lack of respect which he displayed not only by lying to you but reacting badly and turning blame on you when you got upset as well as his choosing to put you down due to a breakdown you had experienced. Not only did he not want to own his lie and show you respect for how that can upset you, he chose to attack you and put you down and discard you. Also, he was in relationships with two women who both had children and he discarded them. Do you want to have a child with him and find yourself discared too?
