Singledom - state of mind?

Singledom vs Coupledom. I often wonder what defines individuals as 'a couple'. Not a very frequent visitor of this expedition, I suffer (yes i mean SUFFER because that's how it ends up being always) from a lack of comprehension and a utter case of turning into a psychopath and my worst nightmare come true.
I've never worked well in this situation, it encompasses a complete 360 shift in my being and from what i 'normally' envision of myself. I don't understand emotions, well that's because most of time I never really need them hence do not understand their use. And being with another person, who you think you're attached to, attracted to, have feelings for, it in inevitable that they tend to crop up here and there. And crop up a bit too much id say. The explanation for which I've stated already.
I can be your best friend, make close to perfect choices for my life, be independent, individualistic, free spirited, ambitious, fun when I'm all by myself.
I do not understand the need for being together, because i still have not understood what togetherness stands for. I don't want to lose out on who I am and yet failing everytime I've quite mastered the art of doing so. And that's why when a third person sees me they cannot imagine me being one of those psycho paths that I turn into , in a relationship, but I do. I do not understand the cat and mouse chase, the emotions, feelings, logic when it comes to picking these in a given scenario which involves a second person, first being you of course. And most of all I don't understand the word 'compromise' and 'adjust' because it is my life and I wish rather demand to live it the way I want to without having to please anyone at the risk of losing yourself or 'sacrificing' as they call it.
It obviously comes from a feeling of being in control, which always leaves me completely helpless with another involved. The part of being physical with emotions and all that jazz just never made sense or took enough priority in my life. I can safely say been there done that and I don't find an incessant need for that because I can quite comfortably live without it, without having a relationship to hold for all those needs.
So I can safely say, I always enjoyed and favoured who I am without anyone because I truly love my life and everyone around me without needing someone to need me.
