Superman, Listen I think we have all been where you are at. Where you just are SO TIRED of the fight and the fact that you get so little response, but that doesn't mean that you can give up!
You are giving up prior to the night even getting here so that you can head off any disappointment that might arrive. The problem with that is that your depression or misgivings about the night will send weird signals to her and your fears will become a self fulfilling prophecy. Remember Hairdog's confidobics?! Do them, today, and pronto.
Tell yourself that you are attractive and virile and ready to go tonight. Be alive and lustful (in moderation, now, don't freak her out, lol) and she has a MUCH better chance of responding to THAT guy. After all, if you are moping around and feeling negative she will be thinking to herself, "Who would want a piece of THAT?!"
If you are confident and irresistable, then regardless of what she does, it will be on HER shoulders. She will be thinking, What is wrong with me? He is SO wonderful!
The alternative could be that she is thinking, Gosh how can he expect me to be filled with desire over a man who is moping and negative and thinks the worst about me?
So chin up, my man. BE THE MAN, no matter what she does. You can do this! Strut around like a peacock, flex your muscles, whatever it takes to get your mojo back.
We're all pulling for you and I don't want to wake up tomorrow morning and read some namby-pamby message about how it just "didn't work out". You make it work out! You deserve this, SD.
