Most Helpful Guy
Leave him. If you think you need to say for the kid, the reality is it will cause him more harm in the end if he watches you grow up unhappy unloved and depraved of intamacy.
Most Helpful Girl
You really should leave, even though as hard as it will be it's what is right for you and your child. It's better for your child to see you be happy instead of thinking that's how a normal relationship should be. You will be happier when you are ready to date again with someone you share a connection with not just a child.
