Ok, were just talking in circles here so lets start over.
My Perspective
I meet a girl. She is intelligent, well educated, and very physically attractive. I get up the courage to approach her and I get her phone number. I call her, get a date with her, and take her out for some dinner/drinks. The first date goes great and we really feel some chemistry between us. I take her home, maybe kiss her goodnight, and thats it. A few days later we have another date. Then a few days after that we go out again. Now were really starting to get close to each other and on our next date she comes home with me and we have sex. By this time I am really falling for this girl and the relationship is becoming serious enough that she asks me to meet her parents.
Im not thrilled about the idea but I know it is important to her so I ride over to meet her at your house. You meet me, decide within the first 5 minutes that you dont like me, and we have a tense dinner where you constantly give me dirty looks and interrogate me about all the things you dont like about me. I dont really understand your hostility so I just assume youre an a$$hole and leave it at that.
Dinner is over, I thank you and her mother for your hospitality and I leave. I then spend the rest of the relationship doing my best to avoid you, you spend the rest of the relationship telling her how Im not good enough, and she is constantly upset because her dad and her boyfriend cant get along. The relationship runs its course and none of your attempts to intimidate me have any impact on the end results.
Your Perspective
You have a little girl and you spend 18-24yrs raising her and doing your best to protect her from harm. One day she mentions that she is dating this new guy and she really likes him. Your dad reflexes kick in and you make it very clear that you would like to meet him so that you can decide whether or not you approve of this random stranger that is suddenly in your daughters life. So you arrange an investigation and disguise it as a casual family dinner. I show up on time but uh oh, Im on a motorcycle. And to make it even worse, its a "crotch rocket" (that always goes over well with dads) So I havent even shaken your hand yet and already there is strike one.
We meet, exchange greetings, and sit on the porch for a while before dinner. Suddenly your daughter and her mother disappear and you are left alone with me. You make a "joke" about having to bury me in the woods if I hurt your daughter and watch for my reaction. I give you a blank stare or maybe even roll my eyes. You think, "This kid has no respect for me and I bet he doesnt respect my daughter either." There is strike two.
We have dinner and you stare at me the whole time evaluating my every move. You completely gloss over the parts where I talk about my background, my education, and my aspirations and you focus on the fact that I dont engage you when you disguise your threats as jokes. That is strike three.
I thank you for dinner, shake your hand, and leave. You spend the rest of the evening debriefing your daughter and warning her of how dangerous I am. She just doesnt get it and she is visibly upset. She continues to date me and you spend the rest of the relationship being frustrated because she just cant see why you know best.
Herein lies the problem. You think taking a girl out on a second date and getting to know her for a "few days" entitles you to sex. THere is really nothing else after sex. Are you willing to marry her? Maybe, maybe not, but I'll tell you one thing, why would buy the cow when you can get the milk for free?
This is widely accepted as "normal" by today's standards, and admittedly, that is how I pretty much operated as a young lad. I won't pretend not to know where you're coming from on this. However, I remember back then those girls that were hard to get and did not "put out". Those were the girls that had, not just "manly" fathers, but smart caring fathers that instilled good sense into them. My feeling is that my daughter is not a holster that you can try for a few weeks and if you don't like her you can change her for a different one. I don't believe my daughters should sleep around with 5 or more different guys before finding "the right one". As much as it contradicts everything I did as a young man, that is exactly where I draw my experience from and exactly the kind of thing I will teach them to avoid. You and many others may find your post above fairly normal, and even reasonable, but I simply won't accept it. If my daughters decide to go against what I have taught them over the years, then I must respect their decision as they will eventually become adults. While I will be disappointed if the situation you describe is the result, I will still love them and make the best of it. Sometimes that's all you can do.
