I hate to say this but Tom Lykis is right about 90% of the women out there (or at least the one's I meet). A bunch of suckubusses who expect you to be their b-tch and then take half your money.
Your comments make me wonder how you portray yourself. Why is it that you seem to attract that sort of woman? Bitterness is not an attractive quality, so perhaps you're wealthy, extremely good looking and have SUCKER tattooed on your forehead? :-)
