It is said that honesty is always the best policy, so the thing to tell them is the simple and unvarnished truth: Daddy couldn't keep his dick in his pants and used the excuse that Mommy was preggers and not putting out enough to meet his needs to rationalize his betrayal. We're not really clear on how he rationalizes his carelessness, but Mommy got herself tested and, thank God, knocking up the trollop was the worst of it... at least he didn't give Mommy AIDS. Mommy, being the saint she is (not to mention seriously naive) forgave Daddy his indiscretion, but we're all going to have to make room in our hearts for the offspring of this union. After all, it ain't the kid's fault his mother is a harlot and his father a lying, cheating piece of shit.

On the other hand, maybe honesty isn't the best policy. Maybe you should just say "child of a previous relationship" without any specifics and let it go with that. People will do the math and reach the obvious conclusions on their own but most will not comment on it if you have clearly made it a point to avoid mentioning the dirty details.

Dingbat! Flirting is perfectly normal. Feeling attracted to someone other than your betrothed is also perfectly normal. Developing a huge crush on some guy you flirted with and felt attrracted to is also perfectly normal - in a teenager. You are too young to be getting married, I suspect, but don't let that stop you. Given your questions and the fact that you sent them to Dear Prudence it seems certain that you are also to damn dumb to be getting married and you're not likely to grow out of that no matter how long you wait.

Sadly, a chastity belt is not going to solve this problem. We live in a more enlightened age. The child needs to get her own damn cell phone however. Unless she is profoundly retarded, she had to know you'd find thiose messages. My guess is she felt uncomfortable discussing openly with you her budding young sexuality and used this as a way of letting you know what is going on in her life. I think if you leave a gift wrapped box on her bed containing a prepaid cell phone, a box of condoms and a bar of soap she'll get the message. Alternatively, you could ship her off to the convent and then hunt down the boy she wanted to shower with and kill him, but as I said, we live in a more enlightened age and that latter course of action could have serious repercussions.

Daddy's Girl;

Holy shit! Your Daddy married one of my ex-wives! And as much as I hate to agree with Prudie, some men seem to habitually fall for shrews. In your father's defense, shrew's often conceal their mean streak until the hook is properly set and the ring is on the finger. Prudie is way off base saying he created the abusive household you fled. His first bitch wife is not abusive because Doormat Dad created anything. She's abusive because she's a shrew. He left many years ago (as evidenced by the two kids he has with bitch wife #2) and found himself with another shrew. But to answer your two questions; You can show your Dad you don't share his wife's low opinion of him simply by being there and not criticizing him - as I suspect you already do. As for step-shrew, just tell her - as bluntly as possible - that every time she starts in on him in your presence she makes herself look like a nasty and classless piece of trailer trash with no breeding or common sense and that unless her entire purpose is to make you loathe her she should just shut the fuck up about her litany of his failings, at least with you.

You poor thing!!!

You weren't invited to the child's wedding because you brought her nothing but pain and suffering, you moron. Maybe one day she'll get past that and you'll both be able to forge some kind of relationship with the kids from the first marriage but don't hold your breath. In the meanwhile, under the circumstances it was gracious of her to even invite her father. I hope he has the sense to go and use the opportunity to make peace with his kids. If not, it's going to be an even longer, colder winter than it needs to be. If being snubbed this way is hurtful to you, consider for a moment how hurtful your presence has been to them from the start and then shut the fuck up. You have no legitimate complaint.
