Is your g/f a conservative,my wife is?
The reason i ask is my male tenant is a conservative while his g/f is a bleeding heart liberal,he says to me we rarely talk politics so it is not an issue..
When i explained it as a way of looking at life and how we live it as a lib or a conservative and it extends way outside of politics.
I swear man you could see the light bulb going on in his head,he started thinking about what they argue over and instantly seen his conservative view up against her lib view.
He sat in the mancave for the next hour mulling over stuff and every so often he would go “ahh that explains”...I said dude you are gonna have to convert her or you will always be arguing over stuff...
A mixed relation like you described is pretty much doomed to fail...you know it too. Outside of possibly great makeup sex, there's nothing there because you have two people with disparate viewpoints of the world.
