When a hero goes too far

I just finished reading a really good book by a really great author. It was the final book in a trilogy of three sisters. The third sister, we'll call her Miss X, was a troubled young woman who didn't believe in love and had her share of men. She didn't believe in relationships and thought men only wanted her for one thing and made it so with her behavior. Until she met our hero. We'll call him jerkface. Okay fine, we'll call him Mr. X.

Anyway, Miss X and Mr. X meet and fall in love, while she is unsure of his feelings for her and insecure of the relationship in general, he is amazed and dazzled that a girl like her would ever fall in love with a guy like him. Are you seeing the recipe for disaster here?

So Mr. X learns from another party that Miss X has cheated on him, and without asking her about it, without confirming it with another source, he assumes that it must be true because of her history with men. Miss X tries to explain to him that it's not true, but of course, she must be lying. When Miss X learns that she's pregnant by Mr. X, he sends her away, telling her that he doesn't care or believe that it's his baby.

So she leaves. She moves out of the city and decides she's going to make it on her own. And she does. When her son is 4 years old he starts asking about his father and instead of lying to him and telling him that he's dead, she decides it might be time to introduce the two of them. See if Mr. X is willing to have a relationship with his son.

Well Mr X. is pissed off. How dare she keep him from his son all this time. She should have tried harder, after all she knew that he didn't believe her. (Pardon me while I barf on all the righteous indignation.) So Mr. X decides to take something away from her, so she'll have a complete understanding of how devastating what she did was to his ego. Err his life? His time with his son? The relationship that he didn't have with his son?

So Jerkface, I mean Mr. X, takes it upon himself to play Miss X for a fool. Let her believe that he still loves her, that they have a chance together so she'll drop her guard and be devastated when he serves her with papers to take their son away from her.

This MIGHT be a forgivable act IF Mr. X realized what a complete stupid jerk head thing this was to do BEFORE he actually served her with papers. Once she's served, in my opinion, this is unforgivable. There is no going back from this, there is no apology that is appropriate, there is no diamond big enough to forgive this. How do you ever trust a man who would do something like this? How do you ever believe that he isn't playing you again? How can ever trust that he's telling you the truth? HOW? HOW? HOW?

What do y'all think? Am I over reacting? That never happens, I never do that, but I might consider it a possibility if you guys say so. Tell me your opinion. Inquiring minds and all that . . .
