THANK YOU ALL FOR YOUR RESPONSES
y'all response so quick and just in time! KANBAN!! i think my problem is solved, she did said sorry to me and turned out that the guy is a WEIRD man. We both live in Sydney, if only the guy live in Sydney i would beat him til death, im a big strong guy
[the guy live in Tokyo].
But what worries me the most is she'll visit Tokyo next year, so i think what's best is just dont think about it, if she do cheat, i'm just gonna get another girlfriend, PRETTIER, HOTTER AND LOVABLE [of course loves me more]
