Seed. Good to see you posting.
I went through a similar experience with my ex.
I moved into her house and helped with her mortgage.
Things were fine while I was employed and kicking in 2k a month. When I got laid off my income dropped and I started working around the house(remodeling) and doing laundry and cooking.
I thought it went both ways but the reality is that a lot of women pay lip service to gender equality but when they start having to be the bread-winner they freak out.
Finally one night she let a hurtful thing slip out: "You're lucky I let you live here"
I would never say something like that to my mate. That's when I knew I had to go.
The rent or mortgage payer has the power. That's the bottom line.
It's almost impossible to build a future with a girlfriend... it's difficult enough with a wife.
