Need advice or Opinions (long, piog)

So a little back story- (I am a single mom of 3) I have been friends with kyle for about 6 months. We have a lot in common and love to hang out. Neither of us had a serious relationship during the time that we had been friends. One night we were hanging out and ended up in bed together. Not long after that we decided to become a couple and see where we would end up. So we started dating 10-9-09. Things have been great. We live about 6 hours apart and he was coming to see me ever weekend, we talked on the phone for hours about everything, when we weren't talking or seeing each other we were texting. I mean we were inseparable via electronics during the week. We had talked about him moving to Bakersfield (we did not talk about me moving because he knows that I have a custody order keeping me here with my twins). Well, Halloween weekend was no different than any other, we had fun hanging out and talking. We knew that he would not be able to come down this weekend because his siblings (who are in foster care) were coming to visit for the first time in months. I was alright with this because I had told him at the beginning that he didn't have to come see me every weekend but that I loved it when he did. So he left my place Monday night and we talked as usual Tuesday and Wednesday. I get up later than him so every morning for the past 3 months or so I would wake up to a text from him saying something along the lines of "Good Morning sexy (he has called me sexy forever), hope you have a great day. Love you." I would reply and then we wouldn't talk till his lunch break at work. We would talk though that and then again around 8pm after he would get home and take a shower. So come Thursday morning (11-5-09) I woke up to no text for the first time in forever. I sent him one anyway and went about my day. I did not hear from him at lunch so I called him. It rang a lot but then went to voicemail. I did not think much of that because I just figured that maybe he had a lunch meeting or something and that we would talk after work. At 5pm I called him ( knowing that I would talk to his voicemail) to tell him something about my birthday weekend (11-15-09 is my birthday) and his phone was off so I just left the message and went about my day some more. At 8pm I called because I am the one who calls at that time but it went straight to voicemail again. I left a message telling him that I miss him and hope that he calls before I go to bed. That was the first day in 3 months that I did not talk to him at all. On Friday I woke up to no text again so I decided to call instead of text...  I heard this: "The number you have dialed has been temperarily disconnected or is no longer in service...." I waited all day to see if I would hear from him. Nothing. So I sent this message to his yearbook: Wondering and worried. I don't know what is going on. I called your phone and I get a message that says that the number is not in service. I called and text you multiple times yesterday and nothing... I have not heard from you. I love you and am very worried. I hope that your alright. I also hope that you find a way to get a hold of me an let me know how things are. I do not want to worry... I am probably just over reacting, but I can't help it. Be safe. I love you. It was read that night but not replied to. Again I waited all day to see if he would contact me somehow. Nothing. So I sent this one last night: I don't know when your going to get this. I don't know IF your going to reply. I don't know if you want to reply. I don't know why you stopped talking to me. I don't know what I did or how to fix it. I think that this list of things that I don't know are things that a girlfriend should know. Yesterday I was so worried about you. That something bad may have happened to you or someone close to you. I mean, why would someone who claims to love another just stop talking to them? Then I got up today and saw that you had been online, that you read my last message and you KNEW that I was worried about you. But for some reason you did not even send a note to say that your fine and that I should not worry. Very inconsiderate. So I went for being worried out of my mind to being mad. All day today I have gone from mad to pissed to crying to angry and so on. If this is your way of ending it, it needs work. If it is something else and I am way off then I need to know. I don't know which way is up as of right now. I do love you... and right now, that hurts like hell. I wont try to change your mind if you want it over. I wont beg you to not do it. I wont cry at you or anything like that. But I think that I deserve to know one way or the other what is going on. Nothing is worse than not knowing. One thing that was even brought up to me is that maybe you did something that you feel guilty about. If that is the case, again.. tell me. Who knows, we might be able to work through it if you want to. Again, read last night and no reply. I think that this is the break up. But not sure. I just don't know. All this a week before my birthday... Happy birthday me. Uggg. I need advice, what do you think is going on?
