Months ago, I kinda hooked up with this guy, but not officially. After 10 days, his girlfriend caught him cheating on her. Well, this guy told me that he didn't have a girlfriend, I knew that he was lying but I pretended that I trust him because I needed to get my mind off of things and I thought maybe he was having some inside problem with his girl. I intended to apologise to his girl cause I feel bad for using him but then it turned out that I wasn't his only side chick. So I decided to back off from their problem and left. I saw this guy recently at a café, he was with his friends but I wasn't sure if he noticed me. I actually really want to say hi and ask how he is doing but I'm afraid that he'll ignore me... what do you guys think?
