I can completely understand your "geek side" and the problems associated with it. It's more or less the same with me except that I have more peace as I was never attractive enough to attract sober women in the first place ;-)
In my mind there's nothing more annoying than friends and family procuring potential partners for somebody and I very much understand your "flight instinct" (must be similar to women fending off meddlesome guys) although IMHO it's better to face that woman instead of avoiding things, events and perhaps persons you might like.

On the other hand I object to the idea what one should or should not do to appear immature. One isn't any more mature because he has a wife - in fact there are lots of husbands and wifes that behave downright irresponsible. In my opinion it's better not to be married than cheat your partner, for example. People marrying only because it suits their jobs or positions are among the most manipulative I can imagine.

It's also interesting what came out of my admittedly stingy remark about the choice of models...

take care,
