Heartbroken-Disappointed

I'm happy about yesterday.. But the happiness totally vanish after i see his skype chatting with some girl and he say he is single.. wat the hell.. is it so fun to let other ppl think that u r single and can play around with girls without let me know it?? It's C-H-E-A-T-I-N-G.. Aiks.. I thought u've change but then nvm la.. Cannot hoping too much cause the more i hope, the more disappointed i'll get.. Now I totally 100% agree on this theory.. More hope more disappointment.. What should I do? Just ignore it? Not easy for me.. Not only saying he is single, he even talk phone with tat girls for hours.. Wat the hell.. Really get so angry la.. Previously already so many girls like that with him, so close till almost can be couple.. I wonder.. Why don't he just break me up since he so wan to be single in everybody's eye?? I wonder...... =(
