Dear God OP, are you so desperate for him that you would actually consider marrying someone so mean.
He's showing you exactly who he is.
I bet his parents are thrilled he's gone from them.
I wonder what attracted him first, to the woman who had inherited a nice house
.
Meanness goes to the very core of who someone is.
It affects everything they do because they are primarily concerned with getting one over financially, with everyone they come across.
Be it buying their round, paying their way, using up other people's food in a house share.
They have no decency nor self respect.
It is absolutely impossible to have a happy, healthy relationship with a mean person.
Their obsession with money comes ahead of everything.
But by all means aim as low as you possibly can, and marry someone like this.
That you are thinking you need a pre-nup, and he is in a month, is hilarious, if it wasn't so sad OP.
Spend some time reading some of the threads on here, of the absolutely miserable lives women lead, trying to raise children with mean men.
Good luck OP, you are going to need it.
