Why Do People always end up disliking me for some reason? Had this problem all my life? Plz help?

Something hit me recently, it's weird, but it seems that this has been an issue for me for most of my life. I'm not sure why this always ends up happening to me but, for some reason, people usually end up disliking me, as a person. Ever since I was in grade school, I was never a bad student, but I have had lots of teachers who did not like me, all the way through, this problem was so bad my parents eventually threaten to sue the county board of education for harassment. Same Problems follow me threw my professional and personal life, my bosses usually end up hating me. I have been fired from every job Ive had, never for anything reasonable. My Wife lately has begun to act the same way everyone else in my life has acted. Within the last 2 years of our 5 year marriage she has began acting as if she hates me, I have tried to talk to her to understand what it is that bothers her, but she never really has any specifics. I'm not an obnoxious person. I'm of mixed ethnicity, extremely well mannered and speak with very good english. Not to sound like I'm bragging but Im' a nice looking man. I did modeling from the point when I was a kid, all the way threw college. I'm not full of myself though by any means, infact I'm very insecure. About my appearance, but try not to let it show. I have a high IQ and a degree. I just don't understand why this always happens with everyone in my life. All my best friends, co-workers, everyone excluding my family has ended up in this boat? And It's driving me crazy. What do you think about this?
