Hi!

Long story short, I used to like this girl very much, but from the very first date there seemed to be no chemistry between us and Mark Manson would say that it wasn't a "fuck yes" from her so after several attempts I just walked away. After she didn't answer one of my messages (after that I didn't send her any more messages and neither did she) I thought that even for a friend she shows very little respect and went to an event without her. Yesterday, she sent me a message saying, "You didn't invite me again". Should I reply?

Even though she lives in her phone, she would often delay her responses for hours and rarely didn't answer at all. Nevertheless, I tried to be friends with her. I don't mean a friend desperately waiting for his crush to change her opinion, but a real friend. We have a hobby (actually, a pub quiz where we are on the same team) and she enjoys spending time there with me and my friends. But I noticed, be it good or bad, that after another game I cannot help analyzing what could have happened if I/we/something blah-blah-blah. So I didn't invite her to the previous game (by the way, a few weeks ago she didn't reply a message from me).
Yesterday, however, she sent me a message on Facebook asking, "You didn't invite me again". Actually, I don't even want to answer that. But today is her birthday, of which I am supposed to know since this is on Facebook. Do you think I should answer anyway?
