When you got into the relationship with Leon you were attracted to his damage..it was internally wrong. You should have firstly been attracted to his humor or even his looks but you say you can fix him..maybe you can or you can’t-

Leon is crying in your arms, he was talking to you about the family he lacked..saying they were killed and he never got to feel cared for since he was a child—

You should have straight away comforted him but no, you were starting to come up with ways to heal him..maybe nurturing him right now would heal him..or at least make him feel better.
