The thing with these threads which reverse a situation to try and prove a point that mn is full of sexist double standards, is that they make the naive assumption that we live in a world that's 100% equal, where men and women behave the same and are motivated by the same things. That just isn't the case. We live in a highly gendered world we're there are vastly different expectations of men and women and we are socialised in different ways since the moment of our birth.
What would I think if I knew a woman who had 3 divorces? Well given that women face a huge amount of social pressure both to marry and to remain married, especially when children are involved, I would assume if I knew no other details that her marriages ended because her husbands were abusive or unfaithful. It's very rare for women to divorce multiple times because they just get bored or fall out of love. Not that it never happens, but the pressure to "make it work" or "stay together for the children" is very strong for women. They are also much more likely to have the majority care of children after a divorce and face stigma for being divorced and for being lone parents. It's not a choice most women take lightly once, let alone multiple times.
What would I think if a man had been divorced multiple times? Well given the prevailing social position that men can walk away from the domestic commitments at the drop of a hat with little to no stigma, and are much less likely to have the main care of children, I would assume in the absence of any other details that (if he left them) he liked the idea of family life but not the reality, or that he was a serial cheat, or (if they left him) that he was utterly unbearable to live with or possibly abusive.
But the stupidest thing about threads like this and the thread that it's copying, is that if you're considering dating someone you don't have to make assumptions about why they're divorced, in fact you shouldnt make assumptions about why they're divorced, you should ask them why they're divorced and then judge them based on their replies.
In the thread that this is copying the op has said that the man's first marriage was when he was very young, his next 2 were 12 years each, and his last girlfriend left him for another man. In his situation I wouldn't judge him at all.
How about you OP? What are the fictional reasons that your fictional potential girlfriend has given for her 3 fictional divorces?
