Judging from many comments here, there's lots of women who are fed up with men and want them to stay away. I assume they had several awful experiences.
But I would like to point out that "It takes two to tango". The one common denominator of all of your relationships is YOU. So maybe the way things went could also be in part your responsibility...?
And I mean this in a totally non-gendered way. Whenever I meet a man who complains about his love life and says women sucks etc. etc., I always reply "Dude, maybe you should learn to choose better partners". ;-)
