Fortunately or maybe unfortunately, depends on how you look at it. I am single and since I now live alone, I don't have to worry about explaining myself to anyone. That being said, everyone who knows me, knows I play poker. They know if they want me to join them for an event or just to go out they must give me a couple of days notice so that I can shift my poker schedule around.
My best friend, does get a little upset every once in awhile. She does understand, that is why we have remained close friends after our living together did not work out almost 2 decades ago.
I will say if I was younger or even if I met someone who I thought was "special" I would make a real effort to make some time for that person. A relationship cannot be a One-way street, where you do whatever you want and your partner just needs to tolerate you. I think society today is not putting enough value on human relationships.
