When you make a decision to have a child you're also making the decision to take responsibility for that child. You don't abandon your obligation as a parent because you have "other plans". I'm over deadbeat parents!
Of course it hurts when you find out it was all a lie and I was just a single piece of his "puzzle" and nothing more. I'm not crazy or "psycho" it's the same term used for all of us when we figure out the truth.
