So I've read essay upon essay from blogs like Rollo's and dozens of individual guys stories on TRP and MGTOW. I think I've found a way to boil the typical relationship arc down to a few simple sentences:

Girlfriend Stage - You should commit to me. It will be great. It will make us both happy. We'll have even more sex. Tons of sex.

Wife Stage - Haha! What a loser! Why would you commit to me?! No more sex for you. Give me money, slave!

...

Am I missing something?
