She seems to be over the moon. He has 4 other children too. I worry about her. Give it some time before hell breaks loose I'm sure.
I'm glad she is happy now. Maybe in spite of the age difference he is a good man and treats her well. But I am skeptical. I always feel bad for people who think they are happy in bad situations. I wish there was a way for them to know how much better life could be if they just waited through the bad. (Not saying this necessarily applies to your friend, but it could).
My cousin posts crap like this all the time, always from a source like, "he ain't no good for you and if he were he never woulda left you you better than that"'s page. WTF.
