Your colleagues probably find your separation odd, and people are generally afraid of odd things, because they don't know what to expect from them.
Your girlfriend's father is probably a little jealous – in the way that he is afraid that someone dear to him might get hurt. Again, he doesn't know what you plan to do to his daughter who was brought up by him with decades of blood, sweat and tears.
And you probably reflect the same suspicion and hostility toward them. Because you are alone, they might think you actually hate them, and because you see they're discussing you, you get paranoid the same way.

I used to be a recluse myself, and I still have issues understanding or empathizing with normal human motives. But then I started meeting people with common interests, and slowly, as I figured out them and myself I became better at understanding and connecting with others, and now I even have a small but profound circle of friends I actually enjoy spending time with.
