if your are a guy, would you try to get the attension of a woman to get to someone else whom you love?...or to make somone jealous?

what if the woman likes you back, would you forget the first one that you loved?

what are some things you would do to get the woman who does not seem to be interested, but you really want her?

ok..this is also in connection with my recent questions. but, i don't get this guy's behavior. yes i know he ignores me for reasons i don't know. i am friends with him and his wife. and he is acting even more strange wit all his sarcastic remarks. recently, we all attended a seminar. and during the break, he came up to me making witty remark about me taking enough notes for everyone. i know he is being clever bcuz he always criticize people for taking a lot of notes when he thinks they are not paying attention to the speaker. so i was like "no..only took notes fo me", while he was walking aways with clever smile, then he doubled back, and said "what was that?"...so i repeated my statement. he Just walk away. i know he is giving his attention to all our other friends and don't even talk with me anymore unless he wants to say something rude to me. i am a young and i have an idea of how people can be so rude. but i just don't understand why this man behaves this way to me. his wife is so opposite from him. she is sweet to me. but he is so mean t me and pass me by as if i m not there. some on, we all have to be around each other. why can't he just be courteous. what did i do? i m 26 yr old female
