from feb.this year,there is a guy who told my colleguae that i am attractive.he left for one week holiday,when he cameback he started to shower me with compliments,praises,gave all the subtle signs of attraction.everytime he got a chance,he's always make me cheerful.he himself told me that he is happy and i make him happy when i am around.affer few months of continous flirting with me,he told in my face that he likes me.i never flirted back because i was not sure if it was true,but still he's not stopping to give all those signs,there was a time he hold my hand and gave me a soft tap on my back which was gently.we message me with x at the end of message.he told me his plans,he was really openened with me.he asked me,he want to have lunch with me in my house,which we did.always there for me to offer his help.i'm worried now because, he is with a girl but apparently he mentioned to me that girl behaving immature,and i 've notice that his face changed,he slightly frown.now i'm confuse,what i'm gonna do?does he has intention to pursue me or what?please help me to analyse the situation. thanks a lot!
