How can I get back in contact with the girl I like?
I am 23 years old and a few months ago I finished university. I have always been very bad to maintain contact with my colleagues when we no longer see each other, it happened to me at school, where I didn't mantain contact with good friends and I didn't talk with them anymore.
Well, in my last semester of university, in one of the classes I met a nice girl. I'm quite shy, and it's always difficult for me to speak spontaneously with the majority of people, but with her it was not like that; almost from the first moment, we got on very well, we talked in class, we laughed and the chemistry between us was one that I had never experienced with a woman.
The semester ended, I no longer returned to the university and as on previous occasions, I let the contact fade away. At Christmas she sent me a greeting on Whatsapp, to which I replied, I gave her my best wishes and she thanked me; that was the last time we communicated by any means. Now, almost half a year after that last communication, I feel that I should not make the same mistake as always, I want to talk to her, that we see each other again, but I do not want her to think that I'm a nuisance or that I'm desperate, so I do not know where to start.
It should be noted that there is a great advantage, and that is that we are friends on Facebook. I'm too shy to talk to her suddenly, for no apparent reason, so I think to greet her for her Birthday, but it's still far away, because it's in five months, and until that time she may have forgotten about me. She is one of the most special people I've met lately, so I do not want ours to fade and feel like a loser for not doing anything about it.
Thank you everyone.
