Ladies (and men) I hate my job and I’m with a G/F who has a really good job.?

I got a job that pays really well. I have a company car, a gas card and I don’t do anything physical, but I hate the type of people I have to work with. I hate getting up in morning and driving home after work (Traffic) I spoke to my g/f about this. She has a 3year old and a 7year old child. She lives in another city about a 45 min drive. Her home is about 3000sf and is in a new neighborhood and home (2007). Her job sends her away for days at time, she loves her job and she makes a thrid more monies then i do and I make damn good money. We talk about her selling her home, move in with me. My home is half the size of hers and it’s an older house in an older nieighborhood. (Not in a bad way the homes were built in the 70′s) my backyard is twice the size of hers. I want to stop working and be a stay at home dad. Plus I want to start buying up homes in the historical district. I have an opportunity to buy one now. If she sales her home we would have the money to do this (Her home is worth almost twice as mine). I want to stop working and stay at home with the kids when she goes to work and goes out of town. She is on board… with some reservations. She’ll be losing her first home and taking a chance in the realestate game. She loves the idea of me staying home with the kids, because it cuts down on daycare and all the after school things that kids have. If I keep my job and keep my income we would be really well off, but her income alone is more then 6 X the average income. I really hate my job and I want to do this. My question is; would you do this? What are things you would be asking yourself ? (NOTE: This is an adult question.)
I like to add the investment income from the homes would bring money in and keep me busy without leaving the kids alone.
SHAYAN FC; I will have income when I start buying homes. I have a home that I am buying, the wheels are in motion as we speak. Would you give this advice if I were a women?
The home I have is more then enough room and the kids could careless about which school they go too. You are with me on this other wise. Thank you.

if you are totally commited to each other you could go ahead with some sort of plans like this. why cant you live in her home if you give up work? it sounds more comfortable and the kids could stay at their school etc. also it sounds like you could live off her income if you stay home. the kids would benefit heaps from you being there for them so its a great idea . dont be trying to get rich. having a nice house and cared for kids is enough for a VERY happy life
