Single all the way for me.
I don't want to change myself for someone (don't try and say that would not happen with the right person - it would. You already change while being with different kind of friends/family members/strangers. Now try to think about how you would change for your lover).
And then there is the thing of spending time together - often. That would actually bring me down. On weekends I don't want to do something but sleep. And on weekdays even less.
I have to admit that I was never in a relationship. My friends told me many times that "if I have someone I love I will want to spend all my time with them".
Good luck with that. Till now I have not met a person I want to be the rest of my life with.
That is of course only my opinion. If you are happy in your relationship that's great.
