I didn't know where else to post this question so I decided to post here. So here goes the story, I hope someone can help (I feel like such an idiot asking).

Okay, I have a friend who lives in the UK and I live in the US. We have been chatting via MSN Messenger. We have met before and have known each other previously. Yesterday was the last time I chatted with him and I did not know we were having issues, but, today I realised a change in him. We normally chat or e-mail each other ever day but, today nothing. I saw he was online so I sent him a IM, no reply. I sent him an e-mail, no reply. So, now I am thinking he has deleted me but, I can see that he is online. So, I went to his profile and it is saying that we are friends on Messenger. Then I went to the, tool>option>privacy thing and I saw that I was not on his contact list. My question, has he deleted me from MSN? Or is he just ignoring me? I wanted to call him but, I don't have anymore international minutes on my phone and won't be able to get any until my next paycheck. So, I really want to know what it is.

I was trying to be optimistic and think that maybe he is just really busy and can't reply right now but, I am a bit afraid cause it is looking like he deleted me and I had made plans to visit him in the UK over the holidays. Have I wasted a ticket?
