I can only talk for my own experiences. I'm on my 3rd husband, unfortunately. 1st husband, who gave me three wonderful kids now 27, 27 & 24 left me for an EX-hooker. If you can figure that one you are more than welcome to comment on it... UGH! and YUCK!! We lasted 7 yrs. (I call him Sperm Provider #1) Second husband, after the 5th year he turned to cocaine and heavy drinking, stole from me which hurt me deeply since he blamed it on my twin boys (later on I found out it was him who did it) Also lated 7 yrs. Present husband who gave me the most beautiful daughter now 8 yrs old. Little did I know he was a pathological liar. Needless to say, you can't believe a word he says and I'm stuck in the marriage. So, all in all, the question you ask is quite hard to answer since everyone has a different reason to NOT remain together. I've always being a "Betty Crocker" housewife. You know, always taking care of the house, making the perfect dinners, doing laundry, raising the perfect children, etc. etc. etc. I feel I'm stuck in a situation I have no control of. Happyness? I know nothing about it. I'm stuck in a very small town where jobs are scarse and not worth a dime since they don't pay much at all. So.... again, I'm stuck with no light at the end of the tunnel.......We've been living in separte rooms for quite a few years now. Happiness...... what is that? Needless to say, I don't believe in straight men. Too much pain has been inflicted in my heart..... Ohhh, the stories I could tell you!!! By the way, if for some miracle I can liberate myself from husband #3, I have already promise myself he will be the last!!!
