I give them about 12 years before the relationship will start to fall apart ... but he'll be unhappy because she will always be dominating everything all the time and very controlling ... in 14 years they'll hardly spend any time together and they'll go their separate ways in 18 years .... but they'll maintain a close relationship for the rest of their lives.
go their separate ways in 18 years
In this economy? She'll probably convince her cuck husband to let him live in their basement for another few years after that because this grifter "can't afford to live anywhere else."
That grifter might even outlive them all and be left with all their possessions and property.
Man she wasted no time! She saw that dude the second he was born and said "sorry hubby I'm on to the hot new shit!"
Send the ungrateful little shit to the mines, like in the good old days.
I'm sure he yearns for those mines, it would be like a treat.
