Romeo,
Either the woman is ignoring you...showing indifference to your care nd concern, or something may have happened to her (I hope not!).
I recently experienced something similar, and it is very hard to come to terms with the fact that you can be feeling so deeply while the other party shows indifference. My questions were met with resentment that I was expecting too much in "daily" contact. So, in my denial, I made all sorts of excuses for his behavior. One tends to do that, accepting lame excuses for lack of response. I was labeled "needy" for expressing love and for desiring that from him, thus, feeling seriously flawed for caring as I did.
Ask yourself if this is what you want in a relationship, long distance or otherwise. My opinion is that some woman would be thrilled to have such an attentive fellow as you.
Read the book , "HE'S JUST NOT THAT INTO YOU." It can be read by men as well as women and shows what you should receive in a healthy, mutually loving relationship.
