How do you call such men?

His ex left him, he came back to his country because he could not bear the break up. The girl likes to do open relationship and the guy was complying unwillingly... when I met him, he did not want to go on dates with me (if he was oki\ with open relationship, he would have gone out with me) Because he was in denial for 4 years and lying to his parents that he was still in a relationship... i was thinking about long term consequence of developing any possible mental illness. I was pushing him to forget that girl but he would not so I got his parents involved. Because I did that, he played me by using my past against me.. to discard me. while doing so, he got me into trouble. How do you call such men?
