Gosh this thread is awesome!
So I've known for ages (and accepted long ago) that I'm an introvert - but this from Bibi and MadBusLady has caused a MAJOR lightbulb moment for me:
Bibi: turning into an anxious, nervous creature in relationships trying to run around pleasing the other person all the time.
MadBusLady: That is definitely me, and I have always suspected it is related to the introvert thing, because I don't instinctively understand how to draw halfway boundaries, as it were. My natural boundary is about one inch in any direction grin. So in relationships in the past I have been inclined, on abandoning the one-inch boundary (which you kind of have to), to let the other person draw the boundaries on how I should behave and what I should do. Fatal if they're an entitled twat!
I have really, really become submerged in relationships in the past as a result of this, and lost my identity in them, because I don't really know how to have an identity that isn't "me on my own". I find it hard enough not being submerged by (highly autonomous, respectful, enlightened, introvert) DP.
Oh.My.God.
It has literally never occurred to me before that my complete uselessness at relationships could be related to my introversion. I've been single for more years than I care to admit - but (pretty much always) very happy being so - because I do not like the person I used to turn into when I was in a relationship.
I'd go from being a strong, independent, happy, at-peace single person and all of a sudden I'd become this blob of jelly on the floor the instant I started a relationship. Needy and insecure and "do you love me? How much do you love me? Do you really love me? WHY DON'T YOU LOVE ME???" Bleagh. Makes me cringe just thinking about it.
Now I just can't be arsed, and to be honest, I have serious doubts as to whether I could actually live with anyone - or even be in much of a relationship at all. I'm just too used to my own space, and my own company. Although, I did read a thing in the paper a few years ago about married couples who lived in separate houses. I could probably do that!
Oh and some of you mentioned children - I have to say, I have always wondered how introverts deal with having kids. It would do my head in!
