Search Results: always a cheater

There's a guy in my workplace that I've been hanging out with. He told me that he likes me and yeah I can feel it because of his efforts and sweet words. He always visit me in my house after work and on his lunch break. Then one day he seems to be cold and not texting me and not visiting me again. I asked him why and he told me that he is just busy. We kept distance to each other for about 1 week. And then I texted him again asking him to hang out with me and my friends. He told me he's tired but he will try next time. While i'm working, one of our common friend told me the reason why he stopped hanging out with me, it's bcs he's living with a girl right now in his dorm. He went to my house that day without knowing that I already knew about him cheating on his GIRLFRIEND. I'm just pretending that i didn't know but the next day he went to hang out with me, i asked him and he said that the girl is just her room mate. and he's not dating that girl. And yeah I'm so stupid cos i believed that bullshit. On my last day of staying in that city, we spent all day together because thats the last time. :( he told me that he likes me but doesn't want to rush a relationship. And now i'm here in a different city, I checked his facebook and found out that he'a really in a relationship with his room mate. I know i don't have the right to act like this but he cheated on that girl and on me! He played with my feelings. Do you think I should confront him?
