Bring it in, BD!
I don't think I have any form of relationshipophobia (It's a word now) but I also understand feeling more comfortable on your own.
I'd say I want the usual in life. Marriage, kids etc. Whether it's a good thing or a bad though, I just don't feel motivated to hurry the process up of actually seeking these things.
One day I may realise I have to speed it up a little and actually be more pro-active but really, being single doesn't cause me any problems. I'm not someone who
needs company, sex, commitment and closeness. I'm happy on my own, I both love and feel I need my own space (and thats seriously the biggest hurdle for me when it comes to relationships) and not once have I even gone out with the sole intent of desperately searching for someone to hook up with. I really do not
need sex enough to make a point of actively going out to get it.
How content I am to be single could very well potentially become an issue one day, I don't know, but I'm not currently unhappy.
