A common thread running through all four of these letters is a breakdown of communication...
Far Away: Your Dad's move to the other side of the country, his failure to invite you to his wedding and the fact that he stopped flying in for visits tend to make me suspect that you have thoroughly communicated how "hurt and dissapointed" you are... not to mention your intense dislike of his new wife and disapproval of his choices. Would you have actually gone to his wedding if you were invited? Would your invitation to visit include his new wife? I'm thinking probably not... If you really want your father to be a part of your life - and your children's lives - I suspect he would be open to that, but not if it means spending the time playing target for you while you rehash your anger and disapproval of him and his life. Even if that anger and disapproval is justifiable, continuing to harp on it is never going to result in a closer relationship between the two of you. Take him as he is or leave him be. Decide whether you want a close relationship with him or want to use him for target practice. You can't have both.
Talk or Deal: Tell him what's on your mind... and listen when he replies. Leaving something you feel so strongly about unspoken is far more likely to destroy your marriage than his looking at a porn movie is. If you can't live with his looking at porn, perhaps he can live without it. If he views it as no big deal, talking about it may help you to stop feeling so upset about it. Or not... Either way, not talking about it is a surefire recipe for disaster. He can't fix it if he doesn't know what's broken.
Tired: You are under no obligation to suffer fools gladly. Communicating to people who ask questions like that that they are being insulting and ignorant is the only way to clue them in that they are being insulting and ignorant. I think you are to be commended for your restraint. I probably would have responded to the "living in trees" question by replying that we lived in huts on the ground so as to be closer to our cooking pots - white folks need to be stirred often or they will burn... Here's your sign...
Waiting: An awful lot of men are completely clueless when it comes to "reading the signals" women send them. Subtle doesn't work. Coy doesn't work. If you arched one eyebrow when you said you didn't have plans for the weekend, he might easily have interpretted that to mean, "And that's the way I want it, bub". Men can be incredibly dense. If you are interrested in a man who asks what your plans are, a far more effective reply might be, "None at the moment... What do you have in mind?". That kind of spells it out for him, and with a great many men that's exactly what you have to do. It also puts the ball back in his court while leaving you with your options wide open in case you don't like what he has in mind. If you don't speak plainly and clearly, the only men you are likely to connect with are the "playas".
