I neither know nor care whether he slept on the floor for a year. I neither know nor care whether his marriage was as good as over before he started seeing the OP. I only know that people can be so narrow minded when it comes to dishing out blame and calling people bad fathers for leaving the mother of their children. But when a woman with kids comes on here to weep and wail about how unhappy she is, how taken for granted, how she can't stand her husband any longer for whatever reason, and she's told to LEAVE LEAVE LEAVE every time.
Absolutely no-one says 'well you've got kids so you'd be an absolutely terrible mother to break up the family home. Terrible. You should just suck it up and stay miserable until your kids are at least 25 or you'll ruin their lives.' Even when women admit to being unfaithful and then immediately try to justify it with some sob story about how awful their ex was and how they had low self esteem because of him, everyone on here just laps it up. 'Oh you poor love, don't blame yourself, you deserve to be happy, you are so brave to admit this.' Blah blah.
It's the double standards that get me every time. The man had an affair and left. He's not a multiple axe murderer. He sounds like a decent father who was unhappy in his marriage, like hundreds of thousands of other people. He spends plenty of time with his DDs and has respected their boundaries and feelings about his new relationship.
It's this constant insistence that he can't possibly be a good man or a good dad, and he must be a player, purely because he had an affair and left his wife. Whether his marriage was already on its last legs or not is irrelevant really, because no-one is prepared to give him the benefit of the doubt on that anyway.
I agree the OP doesn't need to marry him and I'd question whether it's financially prudent for her to do so, if she has her own assets like she says. I think most people with children and a home of their own are far too quick to jump into another marriage, move someone new into their family home or get entangled financially with a new partner when there's no real benefit and it just complicates things for the future. But that's not what the thread is about. It's about his daughters.
