I need help specially to the people who been in love?

i broke with my ex for like a month now.. yesterday thr was dinner for all the college mates and i ended up bumping in to him....i acted as if i didnt see him ...he was showing his bes friend that i was his girlfriend...as his best friend just arrived from states...i went inside the restaurant and my friends wanted me to meet this guy who is a model ..after sitting with him and talking to him my ex enter the restaurant with his best friend i didnt look at him for once but when i did i felt like he was looking at me and this guy...my friend asked him if he was jealous and my ex said i already spoke to Yasmin on the phone i am wishing her all the best in life and she should find someone nice....and he left after this as he wasn't comfortable with environment...he knew the guy i was talking to so he came up to us and said bye to him he also wanted to tell me bye but i didn't look at him...do you think he still have feelings for me?
