confused and frustrated, please help!

Hi April! About a month and half ago or so, I opened up an account on face book and have reconnected with an old friend from high school. At first it was nothing but merely face booking back and forth and then it progressed into him and I sending messages. In one of his message he gave his cell phone number and stated for me to give him a call whenever I wanted to talk. I have yet had the courage to call him, but after an attempt of him trying to reach me through face book via wall to wall, he was unable to get a hold of me. I tried responding a little while later, but there was no response from him, so I decided to text him. Ever since then we have been texting back and forth almost everyday, sometimes hours on end. We talk about the simple things in life, like what we did that particular day, what we plan on doing that night and so on. I admit that sometimes there have been sexual innuendos thrown around but nothing serious. So, what I am confused and frustrated about? I have developed feelings for this guy, which I guess is natural. But it’s almost impossible to do anything about it. For one, he lives in Colorado, and I live in New York. There is obviously no way of knowing how he feels about me just by texting. Of course we joke around and pick on each other, but its hard to tell without him in front of me so I can read his face. I don’t want to jump the gun and have him running for the hills. I’ve already took a chance by telling him that I thought about him more than I probably should, and didn’t know why. I asked him if he thought about me a little more than usual, and he stated that he didn’t want to get too excited because it had only been a week. I really didn’t understand his answer, I guess I was hoping that he would have agreed. I don’t understand how he could not have thought about me a little more than usual since we texted each other practically everyday. I’m actually surprised that didn’t send him running the other way. A few weeks later, I sent him a Christmas card, with a little note inside, including my address, but I haven’t received anything in return. I was just hoping that he would take the time to send me a note in return. The one thing that frustrates me the most is when we’re texting back and forth and he leaves me hanging. I’ll be waiting for a response and he’ll never respond. It’ll be the next day that he explains his disappearance. Usually, work interferes or his friends show up and snag him away. Why doesn’t he let me know then that he had a call, or that he went somewhere? It’s just kind of annoying. I know that texting is very impersonal, and should only be used for short conversations, but I live by it. I really don’t have much to say to warrant a real conversation, so that’s why I do it. I think the biggest reason why I haven’t talked with him on the phone yet is because I’m afraid of losing that excitement, that feeling of the unknown. Actually, I’m not sure if I’m ready to talk on the phone just yet. I know guys brains are wired differently, and he did tell me he is completely clueless when it comes to women. I’m just as clueless about men as men are about women! That’s why I’m turning to you, I just want some insight on this situation. Why am I feeling this way about something that will probably never be? I do want to see him someday, and he did tell me that he does want to come back and visit, but I don’t want to continue to feel this way, especially since there is nothing I can do about it now. Am I throwing this way out of proportion or am I on to something? Any advice would be great. Thank you for your time!
