There's a girl who I first got to know in a course from my college, then we met frequently at work seminars because I worked in a department that collaborates with hers. Eventually we became friends but, to be honest, I ended up having a huge crush on her. Just to put in you into context, I've never had a girlfriend and I had never had so strong feelings like these, there is no comparison with my past crushes. However, the fact that she was in a 4-year relationship always kept me tied up, so I had to learn to cope with the frustration of not being able to do anything about these feelings for her, even though, I think that if I'd had a chance with her then I would have put my shyness aside and, for the first time, would take the lead. Bad news was that those feelings didn't stop growing. She was out of the country for 4-months due to an internship. Although I believed that with this I would be able to clear my heart and mind, from time to time I still tried to keep in touch with her by e-mail because, obviously, I missed her (never mentioned to her the latter phrase). When she came back, I realized that I was wrong, I was feeling exactly the same about her. We met again just to catch up but, to my surprise, one of the first things she told me was that she had returned for just a few weeks and then she would leave the country to study abroad for at least 3 years. One thing I could notice was that, as a side-effect of her new plans, she broke out with her boyfriend. During the time before she left, we met a few more times and I entered into a dilemma: was it sensible to play straight and tell her about my feelings? or should I just stay silent and close this chapter?. In the end I could't tell my feelings for her in person but I wrote a deep and long letter and sent it, along with some gifts, to her new home. In that letter I told her how wonderful was getting to know her, mentioned all the great things she left in my life and how grateful I felt in earning her trust (needless to say all that is true, don't forget she is my friend), but I also expressed, among other things, my real feelings for her, how much I liked her, why I never said or did anything about it, and how much I needed to at least tell her all that so as to release myself and stop suffering. A little more than 3 weeks past between the last time I met her and the time when she received my shipment (she's on the other side of the world). In the meantime I sent some e-mails to her, just as usual, to know how things were going as well as to tell her that I would sent "something" to her. I know that the letter is now in her hands because she had told me that she was notified about the shipment and then told me that she would pick it up on the next day, I have a delivery receipt. It's been almost four days since she picked it up and she hasn't written to me yet (I don't blame her) but now I don't know what to do and if I should write her... at first I thought this need of expressing all my feelings would take me to releasing myself and, as usual, to showing her how much I trust her... but now I'm feeling a twinge of remorse because I wonder if I'll have released a "bomb" on her by opening my heart in such a deep way. What should I be prepared for? How much should I wait before writing to her without seeming to pushy? I'm kind of nervous about her reaction.
