Serious ? help 10 pts.?

i have a confusing situation. i was told for 2 months now that my ex (who has a gf and is leaving her) wanted to talk to me and had still had feelings for me. he told a friend of mine about it but still refused to speak to me. then he said he would see me when i went to his city for a vacation (he lives 4 hrs. away) he kept saying all these mean things about his current gf and that he was leaving her and needed to clear things up with me. then i just recently found out yesterday that he removed my friend from his website and started to get mad in ims saying that not only was his gf crazy but so am i! and he is leaving both of us! wth i havent spokenn to this man in nearly 8 months and i am so confused as to why he would ask for me then do this! i have also just recently found out that his soon to be ex has also found out by reading his emails how he feels about her. (he told my friend that he had already left her) and now she checks his emails and websites everyday. what the hell is going on here is this even normal behavior guys?
