Boyfriend - ex-boyfriend?? confusing me ... wandering eyes! Advice!?

Hi my boyfriend fiance of 9yrs - is in another country (opp side of world 23hrs away by plane). I have been away studying in my home country which we both agreed upon. He has been mad & distant with me past few months. We got engaged last xmas when we last saw each other. Just found out he told friends he split with me 4mths ago! I texted him to find out whats going on??? He has told me its over but sent me y videos of himself so I thought it was just a mood & it will p as its so hard apart ually & intimately frustrating apart & just hope all will be back to normal when I finish study in 2wks & see him in 6wks!!! I just texted him & all I get back from him is a request for a y video of me! Geez! Talk about confusing ... I feel so mad. I have been so loyal & waiting for him & was excited about our future. He told friends he was upset with me cos I had an engagement party without him??!! Not true!!! ... I am so mad & miss with him but it appears to be over.
